Subclaims¶

q2 i? A significant portion of L1/L2 studies reporting high HRV correlations used static devices, which are regarded as more accurate and precise. → Hyun Jin Kim 2024 q2 i? No significant differences in correlation levels of co-measured data and HRV were observed between wristband and chest belt types. → Hyun Jin Kim 2024 (2)

q2 · i? · review · r3

Review synthesis of device use across the 48 studies: the authors observe that a significant portion of the high-correlation (L1/L2) studies used static devices, consistent with literature regarding static devices as more accurate and precise. No test statistic is printed.

"This aligns with our findings that a sig‑nificant portion of L1/L2 studies, which reported a high correlation between HRV and other measures, used static devices."

q2 · i? · review · r3

The review reports no significant difference in correlation levels between wristband and chest belt devices, and cites Menghini et al. (2019) finding wrist-worn sensors accurate in static but less so in dynamic conditions such as speaking.

"Although no significant differences in correlation levels of co‑measured data and HRV were observed between wristband and chest belt types, Menghini et al. (2019) found that wrist‑worn sensors measure HRV accurately in static conditions"
