Table 3 Risk factors identified by a univariate analysis and a multiple logistic regression analysis for delivery < 34 weeks§or < 37 weeksof gestation in patients who had undergone polypectomy

From: Risk factors for spontaneous miscarriage above 12 weeks or premature delivery in patients undergoing cervical polypectomy during pregnancy

  1. §Delivery < 34 weeks: PTB < 34 weeks or miscarriage > 12 weeks, crude: The odds ratio calculated by a univariate analysis, adjusted: The odds ratio calculated by a multiple logistic regression analysis, CI: confidence interval, PP: polypectomy, PTB: preterm birth, *: p < 0.01, **: p < 0.05
  2. Delivery < 37 weeks: PTB < 37 weeks or miscarriage > 12 weeks, crude: The odds ratio calculated by a univariate analysis, adjusted: The odds ratio calculated by a multiple logistic regression analysis, CI: confidence interval, PP: polypectomy, PTB: preterm birth, *: p < 0.01, **: p < 0.05
