Table 3 The final multivariable logistic regression model for the effect of emergency on PONV risk.

From: Emergency open cholecystectomy is associated with markedly lower incidence of postoperative nausea and vomiting (PONV) than elective open cholecystectomy: a retrospective cohort study

Variable Odds ratio (OR) P-Value 95% CI for OR
Urgency of surgery (emergency) 0.103 < 0.001 0.036 to 0.297
Hospital (UHWI) 0.804 0.638 0.324 to 1.994
Female gender 10.451 0.025 1.34 to 81.743
Premedication 0.413 0.042 0.177 to 0.968
  1. The suppressive effect of "emergency" on PONV risk increased from odds ratio 0.176 in the crude bivariate, logistic regression analysis to 0.103 after adjustment for the variables shown.
