1 · What the graph read from it

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.

2 · The registry

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

Heart rate variability (HRV) is a non-invasive measure of autonomic nervous system function and a sensitive marker of physiological stress. Health professions students are exposed to severe academic stress and multiple lifestyle-related factors that may influence autonomic regulation. This study aimed to evaluate HRV profiles in health professions students and examine associations with academic stress and lifestyle factors. A cross-sectional study was conducted among 237 students (81.4% females). HRV was assessed under standardized resting conditions using time-domain, frequency-domain, and Poincaré plot-derived geometrical indices. Autonomic status was classified as normal autonomic function (NAF), low HRV (LHRV), parasympathetic dominance (PD), or sympathetic dominance (SD). Associations with body mass index, smoking, physical activity, sleep quality, and perceived stress were analyzed using chi-square and correlation tests. Normal autonomic function was observed in 65.0% of students, while 35.0% exhibited autonomic imbalance (16.9% PD, 16.9% SD, and 1.3% LHRV). No significant associations were found with lifestyle factors (p > 0.05). Perceived academic stress was significantly associated with autonomic imbalance among females (p = 0.013). In conclusion, most students demonstrated preserved autonomic function, although approximately one-third showed autonomic imbalance. Academic stress was significantly associated with autonomic function, particularly among female students.
