Insofar as administrators can control exits, they may choose which participants will exit or they will choose the date of exit strategically, so that outcomes following date of exit may not be representative of participant outcomes in general.
It should come as no surprise that David Bowie, in full control, exits through the clothes closet, the way he was introduced to so many of us so many decades ago.
Furthermore, the study design of EUREXA was such that patients who did not maintain glycemic control exited the study over time, thus responders may have been selected for.
Therefore, Shp2 is required for intracellular signaling controlling exit of pluripotent mESCs for differentiation into all three germ layers.
Superiority over the historical control was demonstrated, as the upper limit of the two-sided 95% CI for this estimate (35.5%) was lower than the historical-control exit percentage (65.3%; Fig. 2).
The upper limit of the two-sided 95% CI for this estimate (37.8%) was lower than the historical-control exit percentage (65.3%) and was consistent with the primary efficacy analysis (Fig. 2).
The Kaplan-Meier estimate was 27.3%9595% CI 18.4 36.3%) and the upper limit of the two-sided 95% CI for this estimate (36.3%) was lower than the lower limit of the historical-control exit percentage (65.3%).
Even in this more conservative analysis, the upper limit of the 95% CI of the estimated exit percentage at day 112 in the lacosamide 400 mg/day group was substantially below the historical-control exit percentage (37.8% vs. 65.3%).
A sample size of 338 enrolled patients in the lacosamide 400 mg/day group was calculated to provide approximately 90% power for the comparison of the Kaplan-Meier estimate of the percentage of patients exiting by day 112 versus the historical-control exit percentage (65.3%).
11 Superiority over the historical controls can be declared if the upper limit of the 95% confidence interval (CI) for the study drug is less than the lower limit of the prediction interval for the prespecified historical-control exit percentage (65.3%).
