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
Epidemics rank among humanity's deadliest disasters, profoundly affecting societies across health, psychological, social, and economic domains. Past outbreaks have left a unique cultural legacy in the form of epidemic folk stories that explain disease etiology and provide behavioral guidelines during crises. This aligns with theories suggesting that storytelling may serve as an adaptive mechanism facilitating transmission of survival-relevant information. We explored this premise among Indigenous people in West Papua, Indonesia. We interviewed 100 Asmat men, asking them to recall folk stories about past infectious diseases and report their attitudes toward coronavirus disease 2019 (COVID-19). We found that individuals more familiar with epidemic folk stories were more likely to express fear of COVID-19 and adopt social distancing behaviors during the pandemic. Content analysis revealed that these oral narratives emphasized themes such as dietary and good health practices (42%) and hygiene (23%), whereas direct recommendations for social isolation constituted only 12% of identified themes. This pattern suggests that folk stories may not primarily function as precise behavioral instruction manuals, but rather as mechanisms that sensitize individuals to potential disease-related threats. Consistent with this interpretation, exploratory mediation analyses were compatible with the Behavioral Immune System framework, suggesting that folk story knowledge may be associated with heightened sensitivity to pathogen-related cues, stronger emotional responses, and greater behavioral avoidance in threatening contexts. However, the cross-sectional and exploratory nature of our study precludes strong causal or temporal inferences. Longitudinal or experimental research is needed to test these hypotheses and provide stronger evidence for causal interpretation.
