Stone removing efficiency and safety comparison between single use ureteroscope and reusable ureteroscope: a systematic review and meta-analysis.
Article in Translational andrology and urology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundUrologists are gradually beginning to use single-use ureteroscopes (sufURSs), despite a lack of high-level evidence as to their efficacy and safety. This systematic review was registered on PROSPERO (no. CRD42020181808).
methodsThe PubMed, Embase, Web of Science, and Cochrane Library databases were searched for studies published before October 1, 2020. Jadad score tools were used to evaluate the quality of the included randomized controlled trials (RCTs) and the Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included nonrandomized studies. Two researchers independently extracted data according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) principles. A data synthesis was performed using Stata 15.0. Heterogeneity was mainly evaluated with I2 tests. In addition to funnel plots, Egger's and Begg's tests were used to detect publication bias. A sensitivity analysis was also performed. Stone-free rates and postoperative complications were the 2 primary outcomes; operation-time data were also extracted.
resultsSix studies (comprising 887 patients) containing the efficacy data and 5 studies (comprising 952 patients) containing the safety data that were finally included in the quantitative analysis. In relation to stone removal, no significant difference was found in terms of efficacy [Mantel-Haenszel statistic (M-H), relative risk (RR): 1.01, 95% confidence interval (CI): 0.96-1.07, P=0.658) or safety (M-H, RR: 1.30, 95% CI: 0.96-1.75, P=0.093) between the sufURS and the reusable flexible ureteroscope (rfURS), and no significant heterogeneity was found. A publication bias was detected in the efficacy comparison; however, the trim-and-fill analysis indicated that the original synthesis results remained stable.
conclusionsIn relation to stone removal, sufURSs were found to be comparable to rfURS, and no compromising complications were found. However, the results should be treated with caution due to limitations related to the small number of studies included in the analysis.
