Extended Data Fig. 5: Detection of treatment-relevant AF as function of PPG measurement frequency and CHA2DS2-VASc-Score.
From: Smartphone-based screening for atrial fibrillation: a pragmatic randomized clinical trial
Odds ratio for reaching the primary endpoint as function of number of photoplethysmographic (PPG) measurements and CHA2DS2-VASc-Score. Darker colors represent higher odds ratios. The red vertical line marks the number of the 76 scheduled PPG measurements per participant over the six months digital screening phase, the blue line marks the median of the 53 PPG measurements per participant observed in the study.
