From: Physiologic heart rate dependency of the PQ interval and its sex differences
Cumulative distributions of the regression residuals (see the text for details) of the PQ/RR regression models in the top row and of the QT/RR regression models in the bottom row. The panels on the left with red lines show the distribution in females, the panels on the right with blue lines the distribution in males. In all cases, the regressions involved hysteresis corrected RR intervals. The fine dotted lines, fine dashed lines, fine bold lines, and bold full lines correspond to log-linear, linear, hyperbolic, and curvilinear regression models, respectively.
