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
Introduction: Based on four types of poverty defined by the combination of objective socioeconomic status and subjective economic affluence, this study examined the chain mediation mechanism through which political identity is associated with medical students' prosocial behavior via emotion regulation strategies and further explored whether the effects of cultural heritage education (as measured by red music knowledge) differed across poverty types. Methods: A survey was conducted among 1,070 medical students, measuring political identity, emotion regulation, prosocial behavior, red music knowledge, objective socioeconomic status, and subjective economic affluence. To control for the confounding effect of grade level and ensure that all participants had received the same cultural heritage education curriculum, the primary analyses were restricted to second-year students ( Results: (1) Political identity positively predicted prosocial behavior, with a significant indirect effect mediated by the chain mediation pathway of cognitive reappraisal and expressive suppression. (2) Cluster analysis identified four types of poverty: subjectively advantaged, dual-disadvantaged, objectively advantaged, and dual-affluence. (3) Path analysis revealed significant differences across poverty types: In the objectively advantaged type, two independent pathways (political identity direct effect and cognitive reappraisal → expressive suppression) additively predicted prosocial behavior, reflecting a resource additive effect; in the dual-disadvantaged type, the chain mediation pathway was not significant, but red music knowledge indirectly predicted prosocial behavior through political identity; in the subjectively advantaged type, subjective affluence positively predicted prosocial behavior through cognitive reappraisal; in the dual-affluence type, only cognitive reappraisal directly predicted prosocial behavior. Discussion: Political identity is associated with prosocial behavior through a chain mediation of cognitive reappraisal and expressive suppression. This mechanism exhibits qualitatively distinct patterns across the four poverty types, manifesting as four corresponding resource effects: substitution, compensation, additive, and dilution. These findings provide mechanistic explanations for the prosocial function of political identity, extend the application boundaries of the conservation of resources theory, and offer empirical evidence for targeted educational interventions tailored to students experiencing different poverty types.
