Carle's obstetric early warning score as a screening tool for critical care admission.
Observational study in The Indian journal of medical research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesEarly warning systems (EWS) involve serial observations (track) with criteria (trigger) to timely identify patients at risk of complications. Carle designed a statistically based clinically modified obstetric early warning score (Carle's OEWS). This study evaluated Carle's OEWS and its individual components for predicting admission to the obstetric critical care unit (OCCU). Maternal near-miss and maternal mortality were the secondary outcomes.
methodsA prospective observational study was conducted among 1250 pregnant women with a period of gestation ≥28 week admitted in the labour wards of a tertiary centre over 18 months. The physiological parameters of OEWS were recorded and aggregate score was calculated at admission and at regular intervals thereafter, till discharge or OCCU admission.
resultsThe area under receiver operating characteristic (ROC) curve of OEWS was 0.975 for predicting OCCU admission, 0.971 for near-miss, and 0.996 for predicting maternal mortality and was significant for all outcomes. All individual parameters, except diastolic blood pressure, had a significant relative risk for predicting OCCU requirement. INTERPRETATION
conclusionsCarle's OEWS is a useful screening tool for predicting obstetric OCCU admission and can be routinely used in labour wards to ensure timely intervention.
