Comparison of standardized diaphragm ultrasound measurement and conventional methods for predicting weaning failure: a prospective observational study.
Observational study in Journal of anesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeWeaning from invasive mechanical ventilation (IMV) is challenging and has multiple causes. The diaphragm is the main respiratory muscle for inspiration. This prospective study aimed to determine the value of standardized diaphragm ultrasound (DUS) measurements [diaphragm excursion (DE), diaphragm thickness fraction (DTF), diaphragmatic rapid shallow breathing index (D-RSBI), rapid shallow diaphragmatic index (RSDI)] in predicting extubation success in intensive care patients, both individually and in combination with conventional indices [rapid shallow breathing index (RSBI), dynamic compliance (Cdyn), airway occlusion pressure, semi-quantitative cough strength score]. To isolate diaphragm contribution, only neurologically intact patients (Glasgow Coma Scale > 14) with adequate airway protection reflexes were included. The second aim was to examine the relationship between IMV and DUS measurements.
methods151 patients on IMV for > 24 h and eligible for spontaneous breathing trial (SBT) were evaluated. Following exclusion criteria, patients underwent SBT in pressure support ventilation mode (positive end-expiratory pressure 5 cmH
resultsDE and DTF were significantly higher, D-RSBI was lower in patients with successful extubation. There was no difference in RSDI. Multivariate logistic regression was statistically significant, odds ratios (10.018, 1.109, 1.094) were found for DE, DTF, Cdyn, respectively. The only significant correlation between IMV and DUS was DTF-tidal volume (r = - 0.500).
conclusionA standardized multiparametric model, combining DUS with conventional indices, provides moderate predictive accuracy for extubation success. Integrating DUS into weaning protocols can improve extubation readiness.
