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

backgroundAs a safe approach to the upper urinary tract, flexible ureteroscopic lithotripsy (fURL) is a widely accepted treatment for nephrolithiasis. Sometimes, this technique can rely on the natural expulsion of stones, increasing the risk of infections and stone recurrence. To mitigate these issues, some studies tried to use a suctioning ureteral access sheath (S-UAS).

methodsA systematic review was conducted across multiple databases for trials comparing S-UAS with traditional (T-UAS) in retrograde intrarenal surgery (RIRS). The primary endpoint was the stone-free rate (SFR), while adverse effects, operative time, fever rate, and hospital stay were analyzed as secondary outcomes.

resultsWe retrieved 8 articles, encompassing a total of 2,255 patients, with 978 in the S-UAS group and 1,247 in the T-UAS group. Our analysis revealed a higher SFR in the S-UAS group after 1 day, and also at later time points (one or three months) (OR 3.79; 95% CI 1.70-8.46; p = 0.001; I

conclusionOur study suggests that using S-UAS in RIRS may enhance the SFR, and also reduce both complications and hospital stay.

trial registrationThis systematic-review and meta-analysis was prospectively registered on PROSPERO under protocol CRD42024543084.
