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
aimFlexible ureteroscopy (fURS) is a prevalent minimally invasive treatment for upper urinary tract stones, but postoperative fever remains a considerable concern. The precise role of ureteral access sheath (UAS) utilization in influencing infectious complications following fURS continues to be debated. This study aimed to comprehensively evaluate the perioperative and postoperative outcomes of fURS, with a specific focus on the influence of UAS utilization. Furthermore, we sought to identify independent predictive factors for the development of postoperative fever after fURS, utilizing a propensity score-matched analysis to mitigate confounding variables and enhance the robustness of our findings.
methodsThis retrospective cohort study analyzed 486 patients undergoing fURS, with propensity score matching (PSM) used to create balanced UAS (n = 150) and non-UAS (n = 150) groups. Perioperative outcomes and predictors of postoperative fever (defined as ≥ 37.5 °C within 48 h) were evaluated using univariate, multivariate logistic regression, and receiver operating characteristic (ROC) curve analyses.
resultsPostoperative fever rates were comparable between UAS and non-UAS groups (12% vs. 9.3%, p = 0.454), although UAS use was associated with significantly longer hospital stays (median 5 vs. 4 days, p = 0.003). Independent predictors of postoperative fever included positive preoperative urine culture [adjusted odds ratio (aOR) 7.535, 95% CI 2.681-21.175, p < 0.001], elevated postoperative C-reactive protein (CRP) (aOR: 1.211, 95% CI 1.093-1.343, p < 0.001), and increased postoperative white blood cell (WBC) count (aOR: 1.200, 95% CI 1.012-1.424, p = 0.036). ROC analysis demonstrated high predictive accuracy for postoperative CRP (AUC: 0.943) and a combined prediction model (AUC: 0.951).
conclusionsPerforming fURS without UAS did not significantly increase the risk of postoperative fever, supporting its safety in carefully selected cases. Monitoring preoperative urine culture results and postoperative CRP and WBC levels are critical for the early prediction and timely intervention of postoperative fever.
