The reappearance of Chikungunya virus in Bangladesh, 2024.
Article in IJID regions, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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: We investigated a new outbreak of Chikungunya virus (CHIKV) in Dhaka and nearby areas of Bangladesh in 2024, examining its epidemiology, clinical features, and genomic characteristics. Methods: The Institute of Epidemiology, Disease Control and Research enrolled suspected Chikungunya cases from October 19 to December 31, 2024. Reverse transcription polymerase chain reaction was performed, and positive cases were followed up via telephone between days 21 and 28. The E1 gene of 12 samples was sequenced. Results: Of 394 enrolled patients, 138 (35%) were CHIKV-positive, mostly male (64.5%) and over 30 years old (83.3%), with 98.6% residing in Dhaka. Common symptoms included fever (100%), arthralgia (97.8%), myalgia (83.2%), and headache (65.0%). While no fatalities were recorded, 14.5% required hospitalization with an average stay of 5.9 days, and patients lost an average of 10.5 workdays. At 28 days, 81% of 58 follow-up patients had persistent symptoms. Both hospitalization and persistent symptoms were associated with having >4 symptoms initially (incidence risk ratio: 1.14; 95% confidence interval: 1.02-1.27 and 1.19; 95% confidence interval: 1.01-1.39, respectively). Sequence analysis identified an E1-K211E substitution, with phylogenetics revealing a distinct East-Central-South-African (ECSA) sub-lineage compared to 2017 strains. Conclusions: CHIKV is likely to re-emerge in Bangladesh amid the ongoing dengue outbreak, posing a risk of a major outbreak soon. Strengthening efforts to control
