Ultrasound-Guided Small-Caliber Catheter Drainage for Complex Septated Pleural Effusions: Discrimination of Septal Characteristics for Outcomes.

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
Purpose: The objective of this study was to identify the sonographic and clinical predictors of drainage procedure failure using small-caliber catheters under ultrasound guidance for complex septated pleural effusions. Materials and Methods: In this retrospective cohort study, we analyzed 145 consecutive patients who underwent ultrasound-guided small-caliber (6- or 8-Fr) catheter drainage for complex septated pleural effusion at a single tertiary center. Demographic, clinical, and pleural fluid data were collected. Sonographic images were reviewed to classify septation complexity (widespread vs few) and to quantitatively measure septal thickness. Multivariable logistic regression was used to identify independent predictors of drainage failure. Results: Unsuccessful drainage occurred in 79 patients (54.5%). Widespread septations (72.2% vs 36.4%, Conclusion: Quantitative sonographic assessment of septation complexity and thickness independently predicts small-caliber catheter drainage failure in complex septated pleural effusions. Incorporating these parameters into pre-procedural evaluation can aid in risk stratification and guide individualized management, potentially facilitating timely escalation to advanced therapies when indicated.
