¹ These calculations were performed using a power calculator available at: http://www.sealedenvelope.com/power/ ² All calculation were performed for a power of 80% and an α error of 0.05. ³ The mean in the control group is taken from the median control group across studies. ⁴ A six‐hour time difference was chosen to represent a clinically important benefit.
