“…In contrast to susceptibility to bacterial infections, studying the role of sex in the mortality provided contrasting evidence. Some epidemiological studies did not report any gender differences in sepsis-related death (Crabtree et al, 1999;Martin et al, 2003;Laupland et al, 2004;Esper et al, 2006) whereas other found either increased mortality in men (Osborn et al, 2004;Melamed & Sorvillo, 2009;Wafaisade et al, 2011) or women (Combes et al, 2009;Pietropaoli et al, 2010;Nachtigall et al, 2011). As men are also at increased risk of death due to trauma, cancer and cardiovascular diseases as compared with women, the analysis of epidemiological data should integrate these potential biases (Micheli et al, 2009;Pinkhasov et al, 2010;Coronado et al, 2011).…”
