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
backgroundPsychiatric nurses routinely operate in high-stress, high-risk environments, making insomnia a prevalent issue that profoundly impacts their physical and mental well-being, as well as the quality of patient care. Empirical evidence suggests that insomnia not only diminishes occupational performance but also substantially increases the risk, posing a substantial risk to patient safety. Nevertheless, investigations into the underlying mechanisms driving insomnia among psychiatric nurses remain scarce.
objectivesThis study aims to explore the relationship between perceived organizational support and insomnia in psychiatric nurses, as well as to examine the mediating role of psychological capital through the development of a mediation model. The findings are intended to provide novel insights for hospital administrators in addressing insomnia among nursing staff.
methodsA convenience sampling method was used to recruit 475 psychiatric nurses from three tertiary-level psychiatric specialty hospitals in Beijing. Data were collected between March and June 2024 using a general information questionnaire, the Perceived Organizational Support Scale (POSS), the Psychological Capital Questionnaire (PCQ), and the Athens Insomnia Scale (AIS). Statistical analyses included assessments for common method bias, descriptive statistics, one-way analysis of variance (ANOVA), independent samples t-tests, Pearson correlation analysis, and mediation analysis using Model 4 of Hayes' PROCESS macro.
results(1) Of the 475 psychiatric nurses, 395 (83.16%) were identified as experiencing insomnia. (2) The mean scores for perceived organizational support, psychological capital, and insomnia symptoms were 39.11 ± 10.60, 106.35 ± 14.38, and 11.88 ± 5.55, respectively. (3) Perceived organizational support among nurses was positively correlated with psychological capital (r = 0.641, P < 0.001) and negatively correlated with insomnia (r = -0.348, P < 0.001). Additionally, psychological capital was negatively correlated with insomnia (r = -0.369, P < 0.001). (4) Mediation analysis revealed that the total effect of organizational support on insomnia was - 0.335. The direct effect was - 0.191, accounting for 57.01%, and the indirect effect via psychological capital was - 0.144, accounting for 42.99% of the total effect.
conclusionThe prevalence of insomnia symptoms among psychiatric nurses is notably high, and perceived organizational support serves as a negative predictor of insomnia. Additionally, psychological capital partially mediates the relationship between organizational support and insomnia among nurses. These findings suggest that clinical nursing managers may alleviate insomnia in psychiatric nurses by implementing concrete interventions, such as enhancing organizational support through structured programs, and fostering psychological capital via targeted development initiatives and resilience training.
