Real-Time Predictive Analysis of ICU Ventilator Weaning Failure: A Prospective Validation Study.
Article in The clinical respiratory journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo construct and validate a nomogram model for predicting the risk of ICU ventilator weaning failure (reintubation or death within 48 h after extubation) based on multidimensional clinical indicators.
methodsA total of 485 patients in the ICU who needed ventilator weaning were selected and divided into a training set (n = 340) and a validation set (n = 145) at a ratio of 7:3. Baseline data and weaning-related indicators of the patients were collected. Weaning failure (reintubation or death within 48 h after weaning) was regarded as the outcome event. Independent risk factors were screened through univariate and multivariate logistic regression. A nomogram model was constructed, and the model's performance was evaluated using the C-index, AUC, calibration curve, Hosmer-Lemeshow test, and decision curve.
resultsThe weaning failure rate in the training set was 28.53% (97/340), and that in the validation set was 29.66% (43/145). Multivariate regression showed that age, APACHE II score, duration of mechanical ventilation, spontaneous breathing frequency, Glasgow Coma Scale score, and the use of sedatives were independent influencing factors (p < 0.05). The C-index of the nomogram model in the training set and the validation set was 0.829 and 0.826, respectively. The AUC was 0.828 (95% CI: 0.762-0.893) and 0.823 (95% CI: 0.732-0.915), respectively. The sensitivity and specificity were 0.811, 0.751 and 0.662, 0.702, respectively. The calibration curve and Hosmer-Lemeshow test (p = 0.109, 0.402) showed that the model had a good fit.
conclusionThe nomogram model constructed based on the above indicators can effectively predict the risk of ICU ventilator weaning failure and provide a basis for formulating individualized weaning strategies.
