When Omicron knocks at door: An inverted U-shape relationship between virus proximity and prosocial behavior.
Article in Fundamental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The literature suggests inconsistent evidence regarding the influence of danger on prosocial behavior. We explore this issue through a nationwide survey of 8567 households in China during the COVID-19 Omicron variant outbreak in 2022. In a zero-COVID policy, China chose to quarantine all neighborhoods with viral infections. The almost random presence of infected cases provides an opportunity to examine the relationship between the proximity of danger (i.e. potential Omicron infection) and the prosocial behavior of residents in quarantine zones. For the first time, we find an inverted U-shape relationship: residents exhibit a stronger prosocial behavior when living closer to infected cases in the neighborhood, but this positive effect diminishes when they are too close to each other. Furthermore, such non-linear relationship is salient in residents' interpersonal helping but not in their cooperative behavior. Policymakers should be mindful of the different prosocial responses and target their efforts to help communities navigate quarantine periods more effectively.
