Estimating the Incubation Period Distribution of Psittacosis: A Retrospective Observational Study.
Article in Health science reports, 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
Background and Aims: Human psittacosis is a zoonotic disease mainly transmitted by contact with birds. However, the recently identified potential human-to-human transmission indicated an emerging threat of this disease. This study aimed to estimate the incubation period of confirmed psittacosis cases. Methods: We retrospectively collected epidemiological information on confirmed psittacosis cases in Hangzhou City, Zhejiang Province, China, during 2022-2024. Incubation period distributions were estimated from interval-censored exposure and illness onset data using Bayesian parametric models and the Turnbull nonparametric maximum likelihood method. Results: The median incubation period of confirmed psittacosis cases was 11.3 (95% CrI: 8.5-14.2) days with a 95th percentile of 21.8 (95% CrI: 17.8-28.3) days. Conclusion: These estimates could inform clinical diagnosis and would be an important input into mathematical models.
