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

This study aimed to evaluate the impact of nephrostomy tube removal timing on postoperative outcomes in patients undergoing definitive stone surgery after percutaneous nephrostomy (PCN) placement for obstructive urolithiasis. We retrospectively analyzed 159 patients who underwent PCN followed by endoscopic stone surgery between January 2021 and June 2025. Patients were categorized into two groups based on nephrostomy tube removal timing: intraoperative removal (Group 1) and postoperative day 1 removal (Group 2). Demographic data, perioperative outcomes, Clavien-Dindo grade ≥ 3 complications, postoperative fever, and length of hospital stay were compared. Univariable logistic regression analysis was performed to identify predictors of major complications and fever; however, a multivariable analysis to control for potential confounders was precluded by the low event rate. Group 1 (n = 95) and Group 2 (n = 64) were similar in baseline characteristics. Postoperative fever (1.1% vs. 7.8%, p = 0.028) and Clavien-Dindo grade ≥ 3 complications (1.1% vs. 15.6%, p < 0.001) were significantly lower in Group 1. Median hospital stay was also shorter (12 [9-15] vs. 15 [11-19] days, p = 0.008). Intraoperative tube removal was associated with significantly lower odds of major complications (OR: 17.41, 95% CI: 2.17-139.71, p = 0.007) and fever (OR: 7.97, 95% CI: 0.91-69.88, p = 0.061). In patients undergoing definitive stone surgery after PCN placement, intraoperative nephrostomy tube removal is associated with lower complication and fever rates and a shorter hospital stay. This approach may be a safe and preferable option in selected patients.
