Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

List	Outcome	Time frame	Description
Primary	Correlation between early heart rate variability (ln RMSSD) and quality of recovery (ObsQoR-11T)	First 24 hours postpartum	Correlation (Pearson or Spearman, per distribution) between early postoperative HRV (natural log of RMSSD over the first 24 hours) and the ObsQoR-11T total score (range 0-110; higher = better recovery) at 24 hours postpartum.
Secondary	ObsQoR-11T total score	24 and 48 hours postpartum	Obstetric Quality of Recovery score, validated Turkish version (ObsQoR-11T); 11 items, total range 0-110 (higher = better recovery).
Secondary	Subjective sleep quality (Richards-Campbell Sleep Questionnaire, RCSQ)	24 and 48 hours postpartum	RCSQ total score, calculated as the mean of the first 5 items (range 0-100; higher = better sleep).
Secondary	Standard deviation of NN intervals (SDNN)	First 48 hours after cesarean delivery	Time-domain heart rate variability computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform. Reported in milliseconds from analyzable nocturnal 5-minute segments.
Secondary	Proportion of successive NN intervals differing by more than 50 ms (pNN50)	First 48 hours after cesarean delivery	Time-domain heart rate variability computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform. Reported as a percentage of successive interval pairs from analyzable nocturnal 5-minute segments.
Secondary	Low-frequency power of heart rate variability (LF)	First 48 hours after cesarean delivery	Frequency-domain heart rate variability (0.04-0.15 Hz) computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform. Reported as absolute power in squared milliseconds from analyzable nocturnal 5-minute segments.
Secondary	High-frequency power of heart rate variability (HF)	First 48 hours after cesarean delivery	Frequency-domain heart rate variability (0.15-0.40 Hz) computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform. Reported as absolute power in squared milliseconds from analyzable nocturnal 5-minute segments.
Secondary	Ratio of low-frequency to high-frequency power (LF/HF)	First 48 hours after cesarean delivery	Ratio of absolute low-frequency to high-frequency heart rate variability power, computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform. Reported as a unitless ratio from analyzable nocturnal 5-minute segments.
Secondary	Ratio of Poincare plot descriptors SD1 to SD2	First 48 hours after cesarean delivery	Non-linear heart rate variability index computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform. Reported as a unitless ratio from analyzable nocturnal 5-minute segments.
Secondary	Natural log of RMSSD at fixed postoperative time windows	12, 24, 36 and 48 hours after cesarean delivery	Natural logarithm of the root mean square of successive beat-to-beat interval differences, computed from raw beat-to-beat intervals recorded by a wrist-worn wearable (Garmin Vivosmart 5) and processed on the Fitrockr platform, at fixed postoperative windows. Reported as ln(ms).
