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

Objectives: This analysis aimed to evaluate the overall epidemiological situation of diphtheria in Ibb Governorate over 6 years (2020-2025). Methods: This retrospective descriptive epidemiological study reviewed diphtheria cases recorded in the epidemiological surveillance database. The data were analyzed. Results: Of the 721 suspected diphtheria cases, the highest case counts were among females (470; 65.2%), individuals aged 10-19 years (202; 28.0%), in autumn (235; 32.6%), and individuals with an unknown vaccination history (488; 67.7%). The cumulative incidence over 6 years was 21.5 cases per 100,000 inhabitants, with the highest rates observed among females (27.0), individuals aged 20-29 years (27.0), in 2023 (4.9), and in Yarim District (106.6). Additionally, the overall case fatality rate was 4.2% (30 deaths), with more deaths among females (17), individuals aged <10 years (18), and individuals with an unknown vaccination history (25). Conclusion: The continued rise in diphtheria cases in the study area could pose a significant public health challenge, particularly given the fragile health system. Therefore, strengthening early detection, expanding vaccination coverage, improving healthcare services, and intensifying awareness campaigns are essential measures to control this epidemic.
