The cut-off value for lupus anticoagulant positivity was set at 1.2 in at least one of the tests used in our hospital laboratory (Russell’s viper venom test and activated partial thromboplastin); antiphospholipid antibodies were divided into weak (10–40<span class="elsevierStyleHsp" style=""></span>IU/ml) and strong (>40<span class="elsevierStyleHsp" style=""></span>IU/ml) positivity.</p><p id="par0015" class="elsevierStylePara elsevierViewall">Of the 189 patients included, 44.4% were women and the rest men (55.6%), with a mean age of 59 years (SD 15).
