Clinical Characteristics During and After COVID-19 Infection Among Healthcare Workers During the First Wave of Omicron in Chongqing, China.
Article in Immunity, inflammation and disease, 2025. 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
backgroundRevealing the clinical manifestations and associations of COVID-19 before and after negative transition remains an area of significant uncertainty. The aim of this study is to investigate the clinical characteristics observed during and after Omicron infection among a specific population, namely healthcare workers (HCWs).
methodsFrom November 4, 2022, to January 15, 2023, HCWs in our hospital were enrolled to document clinical symptoms, prevention, and treatment for COVID-19 using a structured questionnaire.
resultsA total of 1101 HCWs were included, with SARS-CoV-2 infection detected in 78.20% (861/1101) during the observation period. The median duration for nucleic acid conversion was 8 days. Forty-three symptoms were identified during SARS-CoV-2 infection (11 symptoms per individual). The common symptoms were fever, cough, headache, phlegm production, and fatigue (60.67%-83.29%). These symptoms can be further categorized into five groups: fever type, upper respiratory tract type, influenza type, digestive system type, and systemic type-all showing complex and diverse patterns. Following SARS-CoV-2 infection, a total of 19 symptoms were recorded including four newly emerged ones: reduced lung capacity, memory loss, lethargy, and inattention. Importantly, we observed a significant association between gastrointestinal symptoms during the nucleic acid positive phase and subsequent neuropsychiatric manifestations after negative conversion. Interestingly, females experiencing menstruation or pregnancy exhibited a higher risk of infection, while inhaled vaccines and thymosin demonstrated a protective effect against SARS-CoV-2 infection.
conclusionsThe clinical manifestations observed in HCWs during and after Omicron infection displayed intricate patterns, shedding new light on the complex interplay between SARS-CoV-2 and humans.
