Fig. 2

Graphs a and b show the cuff pressures with (white bar) and without K-Y™ jelly (grey bar) at 24 °C and 37 °C, respectively. Data are expressed as mean (SD) in Graphs a and b. P-values < 0.0167 (0.05/3) were considered statistically significant in the post hoc comparison between the two groups at each time point. Graph c shows the comparisons of inhibitory rates (%) of K-Y™ jelly at 24 °C with those at 37 °C. The horizontal bars, the boxes, and the whiskers represent the median, IQR, and ranges, respectively in Graph C. P-value < 0.05 was considered statistically significant. *P < 0.05, **P < 0.001 and ***P < 0.0001
