From: Physiologic heart rate dependency of the PQ interval and its sex differences
The panels on the top row show the cumulative distribution of individually corrected PQc (left panel) and QTc (right panel) intervals. The left bottom panel shows the cumulative distribution of individually corrected P wave durations. In all these panels, the curves of red and blue lines correspond to the distributions in females and males, respectively. The right bottom panel shows the scatter diagram between the PQc intervals and rate corrected P wave durations. In this panel, the red/pink circles correspond to females, the blue/azure squares to males. The solid red and solid blue lines show the linear regressions between the compared slopes in females and males, respectively. The red shaded and blue shaded areas are the 95% confidence intervals of the regression lines; the violet areas are the overlaps between the confidence intervals of the sex-specific age-regressions.
