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: Staff wellbeing in intensive care units is essential for quality patient care, and nurse staffing configurations can impact nurse sickness absence. The COVID-19 pandemic imposed additional strain on nurses, potentially affecting sickness absence rates. Objective: To examine the association between registered nurse staffing levels, skill mix, and staff sickness absence in intensive care units spanning prepandemic (01/19-02/20), early pandemic (03/20-02/21), later pandemic (03/21-02/22), and post-pandemic (03/22-12/22). Design: Longitudinal retrospective study. Settings: Three National Health Service hospital trusts in England. Participants: Five intensive care units with 6916 sickness episodes from staffing data. Methods: We linked staffing data from electronic rostering systems. Variables included registered nurse hours per patient day, proportion of senior staff nurses with largely hands-on clinical experience, management presence, and sickness absence rates. Generalised linear mixed models analysed associations between staffing configurations in the previous 28 days and sickness absence. Results: The mean sickness absences rate was 2.4 %. When analysing all time periods collectively, an increase in registered nurse staffing by 1 standard deviation (SD) (11.0 h per patient day) was associated with a 5 % reduction in sickness episodes (incidence rate ratio [IRR]=0.95; 95 % confidence interval [CI] 0.90-0.99, Conclusions: Sickness absence in intensive care units decreased with higher registered nurse staffing levels, although this relationship was most apparent post-pandemic. The presence of more senior registered nurses was generally associated with reduced sickness absence, although this relationship proved complex and varied across time periods. Pandemic conditions appear to have altered typical staffing-sickness patterns, with staff sickness being less influenced by workload during the acute pandemic phase. Social media abstract: Study of English intensive care units finds more senior nurses & higher staffing levels linked to reduced sickness absence-key for patient care quality!
