Values of postsurgical events are presented as the frequency and percentage. P values for rates of postsurgical adverse events are determined from a chi-squared test. Odds ratios indicate the relative risk of each postsurgical event in female relative to male patients (reference = 1.0). Unadjusted odds ratios are determined from a univariate logistic regression. Adjusted odds ratios are determined from a multivariable logistic regression that accounts for patient factors demonstrating significant differences between subgroups in Table 1.
For all analyses, significant values in bold and defined as P < .05.
