Predictors of chronic arthralgia following chikungunya virus infection.
Article in GMS hygiene and infection control, 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
Objectives: Chikungunya is a viral illness marked by fever and joint pain. While usually self-limiting, up to 43% may develop chronic arthralgia. The objective of this study is to evaluate the frequency and predictors of prolonged joint pain (>90 d) following Chikungunya infection, with limited data available from North India. Methods: A prospective observational study was conducted at a North Indian tertiary care hospital from September 2023 to December 2023 among adults with lab-confirmed Chikungunya. A total of 56 patients were followed up to 4 months to assess joint pain duration and severity. Data were collected through clinical exams and interviews during initial workup and follow up. Results: All patients had joint pain; 23% reported joint pain lasting for more than 90 days. The ankle was the most commonly affected joint (35.7%), followed by the knee (25%) and metacarpophalangeal joints (21.4%). A comparative correlation between patients of chronic arthralgia and no chronic arthralgia showed significant association with presence of rashes, moderate to severe joint pain and swelling at the disease onset (p value <0.05). Conclusion: In the present study, moderate to severe joint pain, joint swelling, and skin rashes at disease onset were found to be the predictors of prolonged arthralgia.
