Prevalence and Associated Factor of Meningococcal Carriers of Indonesian Umrah Pilgrims.
Article in Journal of epidemiology and global health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMeningococcal meningitis (MM) cases are increasing in 2024. The infection spread widely during mass gatherings, including religious activities like Umrah. In 2023, the total number of Indonesia's Umrah pilgrims was 1.2 million people, much larger than the Hajj pilgrims (209.782 people). Thus, it is estimated that the number of meningococcus carriers also increased. Besides, there is no surveillance system for the Umrah pilgrimage to prevent Neisseria meningitidis from entering the country. The conducted study aimed to describe the proportion of meningococcal carriers among Indonesian Umrah pilgrims and their associated factors.
methodsThe study was cross-sectional among the Umrah pilgrims who arrived via Soekarno-Hatta International Airport and Juanda International Airport. A self-administered questionnaire was sent to each participant and validated at arrival. An oropharyngeal swabs and blood draws (only if symptoms were present) were obtained. RT-PCR examinations were performed to identify N. meningitidis.
resultsThe study enrolled 900 pilgrims with a mean age of 51.34 ± 12.98 (17-79), with 50.9% female. Nearly 9.5% of pilgrims declared having a comorbid disease, and 100% had been vaccinated. N. meningitidis was detected in 201 participants (22.3%) in oropharyngeal swabs as indicator of transmission potential and the need for surveillance.
conclusionsThe analysis data showed that marital status and timing of meningococcal vaccine significantly correlate with meningococcal Carrier. Meningitis surveillance must be done routinely and systematically to decrease the risk of the disease.
