Early Warning Scores for COVID-19 Outcomes: Modified Early Warning Score and Rapid Emergency Medicine Score Performance in Mortality and Hospital Readmission Risk Stratification.
Article in Iranian journal of nursing and midwifery research. 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
Background: The COVID-19 pandemic highlighted the need for rapid and reliable triage tools to predict patient outcomes and support resource allocation. This study aimed to compare the predictive performance of Modified Early Warning Score (MEWS) and Rapid Emergency Medicine Score (REMS) for predicting mortality and hospitalization among COVID-19 patients. Materials and Methods: This prospective cohort study included 900 outpatients and 280 inpatients with COVID-19 who presented to 22 Bahman Hospital in Neyshabur, Iran, between 2022 and 2024. Physiological parameters for both MEWS and REMS were recorded at admission and monitored for 30 days. The receiver operating characteristic curves were used to assess the prognostic accuracy of MEWS and REMS for mortality and hospitalization. Results: At 48 hours before death, MEWS showed slightly better discrimination than REMS (AUC = 74.00, 95% CI: 68.80, 79.20 vs. 73.20, 95% CI: 67.50, 78.90; both Conclusions: REMS demonstrated better prognostic accuracy 24 hours before death, likely reflecting its inclusion of age and neurological status. MEWS showed stronger performance 48 hours before death and in predicting hospitalization.
