Rethinking results from the Japanese 23-valent pneumococcal polysaccharide vaccine randomized clinical trial.
Article in Vaccine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
We review a previously published randomized clinical trial of 23-valent pneumococcal polysaccharide vaccine (PPSV23) that has been used extensively globally to support PPSV23 use among adults. We argue that serious issues with internal and external validity exist that affect the usefulness of these data when evaluating pneumococcal vaccines for the general adult population. As one example of internal data inconsistency, the values reported for the percent of all pneumonia cases due to pneumococcus and the vaccine efficacy (VE) for all cause pneumonia are mutually inconsistent, even based on unrealistically high values for PPSV23 VE against vaccine serotypes and the proportion of pneumococcal pneumonias due to vaccine serotypes.
