Time to oxytocin administration, minutes | –3.3 (–5.2, –1.4) | –2.9 (–5.0, –0.9) |
Abbreviations: CI, confidence interval; RR, risk ratio.
Data for oxytocin administered within 1 minute and 2 minutes report risk ratios from generalized linear models with a binomial distribution and a log link function; data for time to oxytocin administration report change in number of minutes, from linear regression models.
All results use standard errors clustered by provider.
