both the original and expanded Baveno VI criteria necessitate LSM to categorize patients into low-risk or high-risk of having VNT&#46; Despite its advantages of being non-invasive&#44; easy to perform and interpret&#44; LSM requires a specific device&#44; which the cost might be outrageous to many centers&#44; and failure to attain the measurements was reported in some groups of patients&#46; In early 2017&#44; Jangouk et al&#46;

including the elastography-based and stepwise platelet-MELD criteria&#44; for the detection of only VNT&#44; which is clinically more meaningful than any size of esophageal varices&#46; We enrolled only the patients with compensated cirrhosis who would have been most likely to benefit from non-invasive approaches&#44; as they had a low prevalence of VNT&#44; while most of other studies included both compensated and decompensated cirrhotic patients&#46;</p><p id="par0105" class="elsevierStylePara elsevierViewall">There are some limitations in our study&#46; First&#44; despite including various cirrhosis etiologies&#44; the distribution might not reflect the true order of the etiologies in Thailand&#44; as HCV was accounted for the most common cause in this study&#44; in contrast to the earlier established data in which HBV was more prevalent than HCV in Thailand <a class="elsevierStyleCrossRefs" href="#bib0300">&#91;29&#44;30&#93;</a>&#46; Also&#44; the previously published study based on the Nationwide Hospital Admission Data in 2010 <a class="elsevierStyleCrossRef" href="#bib0310">&#91;31&#93;</a> reported that alcoholic liver disease is the most common cause of cirrhosis in Thai patients&#46; This could be due to the fact that our study was conducted in a tertiary care center in which some biases in patients&#8217; referral exist&#44; because in our country&#44; uncomplicated HBV and alcoholic liver disease patients can be treated by general practitioners&#44; while the treatment of HCV needs to be managed by a gastroenterologist or hepatologist&#46; Second&#44; different endoscopists performed EGD and different doctors performed TE&#44; resulting in an inevitable interobserver variation&#59; nonetheless&#44; it might reflect the real-world situation in clinical practice&#46; Third&#44; we collected the data from both retrospective and prospective part in patients whose data were retrospectively collected&#44; the endoscopist and the doctor who performed TE might be the same person or the EGD results might not been blinded to the doctor who performed TE&#44; however&#44; they were unaware of the study aims at that time&#44; making the misclassification of the outcome bias unlikely&#46; And for the prospective part&#44; all the doctors who performed TE were blinded to the endoscopic results&#46; Lastly&#44; although we calculated the sample size in order to evaluate the diagnostic performances of the criteria&#44; and enrolled the patients according to that sample size&#44; the number of patients may not have been large enough to identify the significant differences in missed VNT rates among the 3 criteria&#44; as the missed VNTs were numerically higher in the expanded Baveno VI and stepwise platelet-MELD criteria than in the original Baveno VI&#46; Thus&#44; a larger study should be conducted&#46;</p><p id="par0110" class="elsevierStylePara elsevierViewall">In conclusion&#44; the original Baveno VI criteria have now been validated in many studies and endoscopies could be avoided safely using this approach&#46; From our study&#44; the stepwise platelet-MELD approach might be useful as an alternative method to the Baveno VI criteria in a resource-limited setting where LSM is not widely available&#44; or in patients for whom a measurement cannot be obtained&#46; However&#44; a strong recommendation cannot be made at this time&#46; Future studies should be undertaken from a public health standpoint&#46; Concerning the expanded Baveno VI criteria&#44; although the number of spared endoscopies is consistently high across numerous studies&#44; but missed VNT rates are yet to be validated in a larger study&#46;<span class="elsevierStyleDefList"><span class="elsevierStyleSectionTitle" id="sect0070">Abbreviations</span><span class="elsevierStyleDefTerm">EV</span><span class="elsevierStyleDefDescription"><p id="par0115" class="elsevierStylePara elsevierViewall">esophageal varices</p></span><span class="elsevierStyleDefTerm">GV</span><span class="elsevierStyleDefDescription"><p id="par0120" class="elsevierStylePara elsevierViewall">gastric varices</p></span><span class="elsevierStyleDefTerm">VNT</span><span class="elsevierStyleDefDescription"><p id="par0125" class="elsevierStylePara elsevierViewall">varices needing treatment</p></span><span class="elsevierStyleDefTerm">EGD</span><span class="elsevierStyleDefDescription"><p id="par0130" class="elsevierStylePara elsevierViewall">esophagogastroduodenoscopy</p></span><span class="elsevierStyleDefTerm">LSM</span><span class="elsevierStyleDefDescription"><p id="par0135" class="elsevierStylePara elsevierViewall">liver stiffness measurement</p></span><span class="elsevierStyleDefTerm">plt-MELD</span><span class="elsevierStyleDefDescription"><p id="par0140" class="elsevierStylePara elsevierViewall">platelet-MELD</p></span><span class="elsevierStyleDefTerm">TE</span><span class="elsevierStyleDefDescription"><p id="par0145" class="elsevierStylePara elsevierViewall">transient elastography</p></span><span class="elsevierStyleDefTerm">BMI</span><span class="elsevierStyleDefDescription"><p id="par0150" class="elsevierStylePara elsevierViewall">body mass index</p></span><span class="elsevierStyleDefTerm">HREC</span><span class="elsevierStyleDefDescription"><p id="par0155" class="elsevierStylePara elsevierViewall">human research ethics committee</p></span><span class="elsevierStyleDefTerm">Sn</span><span class="elsevierStyleDefDescription"><p id="par0160" class="elsevierStylePara elsevierViewall">sensitivity</p></span><span class="elsevierStyleDefTerm">Sp</span><span class="elsevierStyleDefDescription"><p id="par0165" class="elsevierStylePara elsevierViewall">specificity</p></span><span class="elsevierStyleDefTerm">PPV</span><span class="elsevierStyleDefDescription"><p id="par0170" class="elsevierStylePara elsevierViewall">positive predictive value</p></span><span class="elsevierStyleDefTerm">NPV</span><span class="elsevierStyleDefDescription"><p id="par0175" class="elsevierStylePara elsevierViewall">negative predictive value</p></span><span class="elsevierStyleDefTerm">HBV</span><span class="elsevierStyleDefDescription"><p id="par0180" class="elsevierStylePara elsevierViewall">hepatitis B virus</p></span><span class="elsevierStyleDefTerm">HCV</span><span class="elsevierStyleDefDescription"><p id="par0185" class="elsevierStylePara elsevierViewall">hepatitis C virus</p></span><span class="elsevierStyleDefTerm">AIH</span><span class="elsevierStyleDefDescription"><p id="par0190" class="elsevierStylePara elsevierViewall">autoimmune hepatitis</p></span><span class="elsevierStyleDefTerm">NAFLD</span><span class="elsevierStyleDefDescription"><p id="par0195" class="elsevierStylePara elsevierViewall">non-alcoholic fatty liver disease</p></span><span class="elsevierStyleDefTerm">AST</span><span class="elsevierStyleDefDescription"><p id="par0200" class="elsevierStylePara elsevierViewall">aspartate aminotransferase</p></span><span class="elsevierStyleDefTerm">APRI</span><span class="elsevierStyleDefDescription"><p id="par0205" class="elsevierStylePara elsevierViewall">aspartate aminotransferase to platelet ratio</p></span><span class="elsevierStyleDefTerm">FIB-4</span><span class="elsevierStyleDefDescription"><p id="par0210" class="elsevierStylePara elsevierViewall">fibrosis-4</p></span><span class="elsevierStyleDefTerm">CTP</span><span class="elsevierStyleDefDescription"><p id="par0215" class="elsevierStylePara elsevierViewall">Child-Turcott-Pugh</p></span></span></p></span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0075">The contributions of each co-author</span><p id="par0220" class="elsevierStylePara elsevierViewall">Study concept and design&#58;
