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
Objective: To investigate the epidemiological characteristics of common human coronaviruses (HCoVs) among populations with acute respiratory infections in the post-pandemic period. Methods: Detection data from the 2024-2025 comprehensive acute respiratory infection surveillance in Jing'an District, Shanghai, were analyzed using descriptive epidemiological methods to assess HCoVs' detection rates, demographic and seasonal patterns, co-infections, and their trends relative to influenza and other common respiratory viruses. Results: A total of 4758 acute respiratory infection cases were included, with an overall detection rate of HCoVs of 4.9% (232/4758). HCoV-NL63 (53.9%, 125/232) and HCoV-OC43 (22.8%, 53/232) were the predominant subtypes. Children under 14 years and adults over 65 years constituted susceptible populations. Different subtypes peaking at different times. HCoV-NL63 was predominant during summer and autumn; HCoV-OC43 in autumn and winter; HCoV-HKU1 in winter and spring; and HCoV-229E was sporadically year-round. Nearly 40% of the detections involved co-infections (38.8%, 90/232), and HCoVs showed alternating and co-circulating trends with other common respiratory viruses. Conclusions: HCoVs exhibit subtype-specific predominance in different seasons, with frequent co-infections and a substantial burden in children and the elderly, supporting the need for integrated surveillance and targeted protection.
