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 This study explored the performance of bedside ultrasound monitoring of diaphragmatic function in predicting the ventilator weaning outcomes of patients with cervical spinal cord injury. MATERIAL AND METHODS The clinical data of 136 eligible patients hospitalized from December 2021 to December 2023 were obtained for this prospective study, and they were assigned into weaning failure and weaning success groups. Intergroup comparisons were conducted on the general data and diaphragmatic function parameters: diaphragm excursion (DE), diaphragm thickening fraction (DTF), diaphragm contraction velocity (DCV), diaphragmatic-shallow rapid breathing index (D-RSBI), diaphragmatic thickness at the end of expiration (DTee), and diaphragmatic thickness at the end of inspiration (DTei). RESULTS Among the diaphragmatic function parameters, decreases in DE and DTF but increases in DCV and D-RSBI were observed in the weaning failure group compared with those in the weaning success group (P<0.05). There were no significant differences in DTei and DTee between the 2 groups (P>0.05). The areas under the receiver operating characteristics (ROC) curves of DE, DTF, DCV, and D-RSBI alone and their combination for predicting ventilator weaning outcomes were all >0.70, and the combination had the highest predictive value. The combination of DE, DTF, DCV, and D-RSBI was superior to the 4 parameters alone in terms of the net benefit for predicting ventilator weaning outcomes in the threshold ranges of 0-0.842, 0.843-0.878, and 0.907-1.000. CONCLUSIONS Bedside ultrasound monitoring of diaphragmatic function parameters DE, DTF, DCV, and D-RSBI has good predictive value for the ventilator weaning outcomes of patients with cervical spinal cord injury.
