1 · What the graph read from it

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.

2 · The registry

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 characterize dynamic changes in the weight-adjusted rapid shallow breathing index (RSBI) during a 60-min spontaneous breathing trial (SBT) in mechanically ventilated preterm infants and evaluate its predictive value for weaning outcomes. STUDY

designThis retrospective study included preterm infants undergoing SBT in a neonatal intensive care unit. Patients were classified as successful or failed weaning based on reintubation or escalation of respiratory support within 48 h. Weight-adjusted RSBI [f/(Vt/kg)] was calculated, and parameters at multiple SBT time points were compared. Receiver operating characteristic analysis assessed predictive performance.

resultEighty-six infants were enrolled (58 successful, 28 failed). Baseline characteristics were comparable. RSBI increased significantly after 30 min in the failed group. At 60 min, RSBI was higher in failed infants (16.31 ± 3.82 vs. 9.79 ± 2.15; P < 0.001). Predictive ability was high (AUC 0.892; sensitivity 85.7%; specificity 82.8%).

conclusionRising weight-adjusted RSBI during late SBT predicts weaning failure reliably.
