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
The increase in the retrograde intrarenal surgery (RIRS) has been accompanied by the increase in complications. This study identified the factors that affected the severity of the complications using the modified Clavien classification system (MCCS). Three hundred and twenty-two consecutive RIRS performed by a single surgeon were analyzed. Data collection included demographics, clinical parameters, and perioperative and postoperative complications. The rate of adverse events for each of the Clavien grades was calculated, and statistical comparisons were made. The impact of each of the factors on the severity of the complications, based on the MCCS, was investigated using the univariate and multivariate analyses. The total complication rate was 26.1% (MCCS: I = 67.7%, II = 22.7%, IIIb = 7.2%, IVb = 2.4%). On the univariate analyses, the following factors affected complication: positive preoperative urine culture, operative time, irrigation rate, and stone burden. Multivariate logistic regression analysis demonstrated that positive preoperative urine culture, irrigation rate, and operative time were the significant factors affecting the complications. Most of the RIRS complications were in the lower Clavien grades and major complications were uncommon. Positive preoperative urine culture, irrigation rate, and operative time were the factors that affected complications.
