We compared the incidence of postoperative complications in women (vs.
men) in 4173 patients. Overall, women were almost twice as likely to
report any postoperative complication (RR = 1.92, p < 0.0005). Specifi
cally, they were 2.6 times more likely to report nausea and vomiting (
p < 0.0005), 1.5 times more likely to report sore throat (p = 0.0001),
2.3 times more likely to report headache (p < 0.0005) and 2.4 times m
ore likely to report backache (p = 0.0036). Whether these gender diffe
rences are due to a reporting bias, or whether in fact women are at gr
eater risk of such complications, remains to be determined.
