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
Vaccines against influenza, pneumococcal pneumonia, and herpes zoster are pivotal for infectious disease control in older adults, yet vaccination coverage remains suboptimal. Guided by Protection Motivation Theory (PMT), this cross-sectional study identified cognitive factors of overall willingness toward the three important vaccines among adults aged ≥60 y, to inform population-level intervention strategies. A representative sample of 420 older adults was recruited from Chengdu, China, via multistage stratified sampling between August and October 2024. Partial least squares structural equation modeling was applied to analyze associations between PMT cognitive constructs, health status, and overall vaccination willingness. Results showed moderate overall willingness to receive the three vaccines (16.7 ± 5.0, range: 5-25), with PMT explaining 57.6% of its variance (R
