REGRESSION, SECONDARY
All research subject groups assigned in this study are referred to as ITT (Intention to treat). Of the ITTs, the research subjects for whom data on the primary endpoints have been obtained are referred to as full analysis set.The total dose of pethidine hydrochloride, a concomitant analgesic, is tabulated for each group. Using a Poisson regression model with the total dose unit of pethidine hydrochloride as the objective variable and the group as the explanatory variable, the ratio of the mean total dose units for each group, the 95% confidence interval based on the Wald statistic, and the bilateral Summarize each group appropriately according to the scale of each endpoint, and use a Poisson regression model with each secondary endpoint as the objective variable and the group as the explanatory variable, as in the case of the primary endpoint, for each group. Calculate the mean total unit ratio, 95% confidence interval and bilateral
