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

Measles is a vaccine-preventable infection that can lead to serious illness and death. The delayed implementation of the World Health Organization (WHO)-recommended two doses of measles-containing vaccine (MCV1 and MCV2) and immunity gaps compromise the effort to elimination. Eighteen years (2006-2023) of surveillance data from Gabon measles surveillance program were collected and analyzed. Variables included age, sex, vaccination status and date, disease date, and anti-measles immunoglobulin M (IgM) status (determined by immunoassay). The rate of infection and association studies was done. Results showed that 60.6% (1,640/2,708) of suspected cases were unvaccinated against measles. Of suspected cases, 26.1% were laboratory-confirmed cases. Unvaccinated individuals were 5.9-7.7 times more likely to be anti-measles IgM positive (
