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: Several epidemic outbreaks have affected the Zinder region. These include diseases targeted by the expanded immunization program and other emerging diseases. This study aimed to analyze these epidemics. Methods: This is documentary research of the epidemics of meningitis, measles, cholera, COVID-19, and diphtheria, which occurred in the Zinder region from 2015 to 2023, as well as their determinants. The data collection is made from the linear list of notifiable diseases of the Regional Directorate of Health and Public Hygiene of Zinder, associated with literature review on the determinants of the appearance of these epidemics. Results: The number of meningitis cases has gradually increased in Zinder from 2019 to 2024. A total of 5019 cases were registered during these epidemics, with a mortality rate of 6.31%. Five measles epidemics have been recorded since 2015. A total of 13,887 cases were notified during these epidemics, with a mortality rate of 0.30%. Three cholera epidemics occurred: in 2021, in 2022, and in 2024. During these epidemics, 884 cases were recorded, with 24 deaths or a lethality of 2.71%. The COVID-19 epidemic occurred in 2020, with 364 cases, including 17 deaths, i.e. a mortality rate of 4.67%. Since 2022, the region has been facing a diphtheria epidemic. A total of 3310 cases has been reported, with 173 deaths. The causes of these epidemics are multifaceted; they involve the decline in vaccination coverage, migration, insecurity, the COVID-19 pandemic, and climate change. Conclusions: The impact of epidemics on the health of the population and the socio-economic development of regions implies a greater mastery of the root causes mentioned in this study.
