Influence of day-night and weekday-weekend differences on rapid response team performance in in-hospital cardiac arrest.
Observational study in Revista da Associacao Medica Brasileira (1992), 2026. 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
objectiveThe aim of this study was to compare the return of spontaneous circulation and survival to discharge of patients who experienced in-hospital cardiac arrest assisted by a rapid response team during the day versus night and weekdays versus weekends.
methodsThis retrospective observational study was conducted at a tertiary teaching hospital. Patients aged 18 years or older who experienced a cardiac arrest in the wards between March 2018 and December 2021 were included. Patients with an express order of "natural death permission" were excluded. Data regarding the period of in-hospital cardiac arrest occurrence, return of spontaneous circulation, and survival to discharge were collected from medical records. In addition, data related to nursing staff leave were collected.
resultsA total of 387 patients were included in the analysis. The mean age was 65.4±14.8 years, and 53.7% were men. In the multivariate logistic regression, in-hospital cardiac arrest during the day versus night was not associated with return of spontaneous circulation. However, in-hospital cardiac arrest during weekdays versus weekends showed a significant association with return of spontaneous circulation (odds ratio=2.073; 95%CI 1.206-3.564; p=0.008). No differences were found in survival to discharge between daytime versus nighttime or weekdays versus weekends.
conclusionThere is no difference in return of spontaneous circulation rates between in-hospital cardiac arrest events occurring during the day versus night. However, a significant difference in return of spontaneous circulation rates was observed between weekdays and weekends, although this difference did not extend to in-hospital survival rates.
