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

Background: Following a major chikungunya outbreak in Foshan City, China, locally transmitted cases have been reported across the country. Research remains limited to epidemiology, transmission dynamics, vector characteristics, and risk factors of chikungunya fever. Methods: We analyzed 164 chikungunya cases reported in Quanzhou City, Fujian Province, between August 18 and September 9, 2025, along with mosquito surveillance data collected from August 25 to September 13, 2025. We examined case characteristics, symptom patterns, Cycle threshold (Ct) values trends, and vector distributions. Logistic regression was used to identify demographic factors and mosquito density indices associated with infection risk. Results: Among 164 cases, 50.0% were male and 38.4% were aged ≥ 60 years. Ct values were significantly influenced by age ( Conclusion: Chikungunya disproportionately affects older adults, especially those aged ≥ 70 years. Viral load increases with age and decreases with delayed diagnosis. The lack of correlation between symptoms and viral load may suggest that asymptomatic individuals could be equally infectious, providing guidance for the screening and management of high-risk populations.
