What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The menopausal transition is associated with hormonal, cognitive, and autonomic changes, yet the interplay between cognitive function and autonomic regulation-measured via heart rate variability (HRV) remains underexplored in Indian women. Aims: The study aimed to compare cognitive performance and HRV parameters between reproductive-age and post-menopausal women, and to assess the relationship between cognitive domains and HRV indices. Methods: A cross-sectional study was conducted at a tertiary care center of Northern India, enrolling 240 healthy women (120 reproductive-age, 20-40 years; 120 post-menopausal, 45-60 years). Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), while HRV was evaluated via 5-min resting ECG. Time-domain [standard deviation of NN interval (SDNN), root mean square of successive differences (RMSSD), proportion of NN50 (pNN50), mean RR] and frequency-domain [low-frequency (LF) and high-frequency (HF), LF/HF ratio] HRV metrics were analyzed. Results: Post-menopausal women showed significantly lower MoCA scores than reproductive-age women (22.35 ± 3.17 vs. 25.54 ± 2.34, Conclusion: Post-menopausal women exhibited cognitive deficits-particularly in executive and memory domains-alongside distinct alterations in autonomic function. Contrary to expectations, HRV parameters indicated preserved or enhanced parasympathetic modulation in the older group. These findings underscore the relevance of autonomic-cognitive coupling in aging women and support HRV can be a potential biomarker of cognitive health.
