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
backgroundInvestigating the mediating role of maladaptive cognitive-emotional regulation strategies in the association between psychological vulnerability and psychological capital among family members of patients in infectious diseases intensive care units (ICUs) holds important clinical relevance and practical value for clinical nursing practice, given the unique challenges posed by infection control measures, restricted visiting and the psychological burden associated with infectious diseases.
aimTo evaluate the mediating role of maladaptive cognitive-emotional regulation in the relationship between psychological vulnerability and psychological capital among families of ICU patients. STUDY
designA cross-sectional survey.
methodsThis study included family members of patients admitted to the ICU as study participants. The study measures comprised a general demographic information questionnaire, the Psychological Vulnerability Scale, the Positive Psychological Capital Questionnaire, the Cognitive Emotion Regulation Questionnaire and the Acceptance and Action Questionnaire.
resultsA total of 211 family members of patients in the infectious disease ICU were included. Descriptive statistical analyses yielded the following mean scores (± standard deviation): psychological capital 122.22 ± 24.50, psychological vulnerability 46.47 ± 15.57, maladaptive cognitive-emotional regulation strategies 19.26 ± 8.64 and higher scores on the psychological flexibility measure indicating lower flexibility (greater experiential avoidance) 17.78 ± 10.13. Hierarchical regression analyses demonstrated that psychological vulnerability was a significant direct negative predictor of psychological capital (β = -0.261, p < 0.001, 95% CI [-0.405, -0.117]). Additionally, maladaptive cognitive-emotional regulation strategies exerted a significant partial mediating effect on the association between psychological vulnerability and psychological capital (β = -0.128, p < 0.01, 95% CI [-0.244, -0.042]), accounting for 24.76% of the total predictive effect of psychological vulnerability on psychological capital.
conclusionPsychological vulnerability shows both a direct negative association and an indirect association with psychological capital, with maladaptive cognitive-emotional regulation strategies mediating the relationship between the two constructs. RELEVANCE TO CLINICAL PRACTICE: These findings highlight that critical care nurses should prioritize regular monitoring of the psychological status of infectious diseases ICU patients' family members and are well-positioned to deliver brief, targeted psychological interventions to alleviate their psychological distress.
