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
backgroundHuman papillomavirus (HPV) causes substantial disease burden among gay, bisexual, and other men who have sex with men (GBMSM), yet HPV vaccination pathways for men remain evolving in mainland China. PURPOSE: To apply a culturally adapted, extended Information-Motivation-Behavioral Skills (IMB) model to identify psychosocial pathways associated with HPV vaccine acceptability among Chinese GBMSM.
methodsA cross-sectional online survey was conducted between December 2024 and January 2025 among 1,045 GBMSM living in mainland China. Measures included HPV-related information, health beliefs, anticipated regret, subjective norms, self-efficacy, and HPV vaccine acceptability. Measurement and structural equation models estimated direct and indirect pathways.
resultsHPV vaccine acceptability was moderate (mean 3.40, SD 1.14). Subjective norms were the strongest predictor of acceptability (β = 0.68,
conclusionsHPV vaccine acceptability among Chinese GBMSM was shaped predominantly by social norms, with self-efficacy acting as a key pathway through which psychosocial factors were associated with acceptability.
