a,b, MAPE values at the participant level of PHRM and 15 baselines by skin-tone group in diverse laboratory (a; n = 44, 25 and 35 participants in the light, medium and dark skin-tone groups, respectively) and free-living (b; n = 39, 29 and 39 participants in the light, medium and dark skin-tone groups, respectively) conditions. Deep-learning baseline models were trained on the PURE (ending with -P) and RLAP (ending with -R) datasets. Filled bars indicate MAPE on valid HR measurements after gating on the confidence scores associated with the PHRM predictions; empty bars indicate MAPE on all videos without any gating. Red dashed lines indicate the prespecified accuracy target of MAPE <10% according to the ANSI/CTA-2065 standard. Error bars are upper 95% CIs.
