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
backgroundHealthcare workers (HCWs) are at occupational risk from COVID-19. Understanding the profile of infected HCWs is important to guide workplace protections.
objectivesTo describe the demographic and clinical characteristics of HCWs infected with COVID-19 and to examine factors associated with vaccination status among infected HCWs.
methodsThe study design was cross-sectional, using medical records from health workers working in a tertiary teaching facility in Gauteng, South Africa, from 12 May 2021 to 11 May 2022. The data were analysed using univariate and multiple logistic regression analysis. Statistical significance was set at
resultsA total of 1235 HCW records were included. The age ranged from 17 to 64 years. The median age was 38 years (IQR: 32-48). Nurses accounted for the largest proportion of cases, followed by healthcare assistants and physicians. Female sex, older age, and comorbidity were associated with higher odds of being vaccinated among infected HCWs.
conclusionsThis study provides a descriptive profile of HCWs infected with COVID-19 during the third and fourth wave transition in South Africa. The findings highlight demographic and clinical factors linked to vaccination status among infected HCWs and underscore the continued need for infection prevention and control measures to protect frontline staff.
