Imported Malaria Outbreak in Military Personnel Returning from Peacekeeping Operation in South Sudan - Thailand, 2023.
Article in The American journal of tropical medicine and hygiene, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Malaria remains a global health concern, with Thailand primarily experiencing cases in border areas and from imported infections. During the third rotation of Thai peacekeeping troops returning from South Sudan between June and November 2023, a malaria outbreak was reported. In response to the outbreak, we conducted a retrospective cohort study, in which we identified 46 confirmed cases of malaria, with 27 occurring postdeployment. The most common species were Plasmodium falciparum (n = 19) and Plasmodium ovale (n = 16), with a median postdeployment time to first symptom of 14 weeks (interquartile range: 9-28). The analysis revealed that those relying on informal sources for malaria knowledge, such as friends, were at higher risk (hazard ratio: 4.92; 95% CI: 1.97-12.28). Challenges with prophylaxis adherence and glucose-6-phosphate dehydrogenase deficiency-related hemolysis were identified. This study calls for improved malaria prevention in South Sudan, better postdeployment monitoring, enhanced education for troops, and research on terminal prophylaxis to reduce cases.
