1 · What the graph read from it

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.

2 · The registry

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

Pneumococcal vaccination effectively reduces the incidence of pneumococcal pneumonia and the associated mortality rates in older adults. Understanding trends in coverage and the influencing factors is essential for optimizing future vaccination programs. Two cross-sectional surveys were conducted in October 2022 and September 2024 among residents aged 60 and above in Pudong New Area, Shanghai. Data on demographic characteristics, pneumococcal vaccination status, and reasons for either receiving or not receiving the vaccine were also collected. A generalized linear mixed model (GLMM) investigated temporal trends in vaccination rates, adjusting for sociodemographic factors. Interactions with the survey year were evaluated to identify associated with time-varying effects on vaccination. The pneumococcal vaccination rate was 34.8% (95% confidence interval [CI]: 32.9-36.6) in 2024, a significant increase of 10.6% points from 24.1% (95% CI: 22.4-25.8) in 2022. (
