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
backgroundPremenstrual syndrome (PMS) refers to a range of physical and emotional symptoms occurring during the luteal phase of the menstrual cycle. It is closely linked to hormonal fluctuations, menstrual physiology, and lifestyle factors, and can significantly affect quality of life. This study aimed to investigate the prevalence of premenstrual syndrome symptoms and its associations with perceived stress, physical activity, and dietary quality among college students at a university in Hainan, China.
methodsA self-administered, structured questionnaire was used to collect data on socio-demographic and menstrual characteristics, perceived stress, physical activity and dietary quality. Self-reported PMS symptoms were assessed using the Chinese version of the Premenstrual Syndrome Scale (PMSS). Perceived stress was measured using the 10-item Perceived Stress Scale (PSS). Dietary quality was evaluated by calculating the Chinese Healthy Eating Index (CHEI) from a food frequency questionnaire. Physical activity levels were assessed with the short form of the International Physical Activity Questionnaire (IPAQ-SF). Data were analyzed using SPSS 26.0, with chi-square and Mann-Whitney U tests for group comparisons, and linear regression to assess factors associated with PMS symptoms score.
resultsThe prevalence of self-reported PMS symptoms among college students was 32.9%. In the multivariate linear regression model, perceived stress score was positively associated with PMS symptoms score (B = 0.378, p < 0.001). Moderate-intensity physical activity (MPA) was negatively associated with PMS symptoms score (B = -0.087, p = 0.037). Among the components of the CHEI, higher red meat score (indicating lower intake) was significantly associated with lower PMS symptoms score (B = -0.436, p = 0.007).
conclusionThe findings highlight psychosocial and lifestyle factors as important correlates of PMS symptoms and provide preliminary evidence to inform nursing screening and health promotion initiatives in campus health services. Longitudinal studies are needed to further explore these associations.
