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
Introduction: Bladder cancer is a common cause of morbidity and mortality worldwide. The primary treatment for intermediate and high-grade non-muscle-invasive bladder cancer (HS-NMIBC) involves the bladder preservation approach (BPA) transurethral resection of bladder tumor (TURBT) followed by intravesical Bacillus Calmette-Guérin (BCG) immunotherapy. For BCG-unresponsive patients, radical cystectomy (RC) is the gold standard. Materials and Methods: A comprehensive literature search was conducted on PubMed, Scopus, and Cochrane Central to identify relevant studies. Eligibility criteria used were patients suffering from HS-NMIBC and studies that exhibited the comparison between the BPA and RC followed by TURBT. All analyses were conducted using Review Manager version 5.4, and the statistical significance level was set at Results: This systematic review and meta-analysis included five studies. The most prominent outcomes being assessed were overall survival (OS) between BPA and RC at intervals of 2 years, 5 years, and 10 years and cancer-specific mortality (CSM) between BPA and RC at intervals of 2 years and 5 years. OS showed insignificant results at 2 years (RR 0.79, 95%CI 0.95-1.30; P = 0.19), RC favoring OS in 5 years (RR 1.17, 95%CI 1.10-1.24; Conclusion: Both approaches prevent CSM and progression from HG-NMIBC; bladder preservation with BCG may be a superior strategy when compared to RC. The former approach improves OS notably in the elderly and those with T1G3 tumors. However, RC may still be a preferable alternative for the younger population. Despite this, determining the optimal BPA method remains a challenge and future high-quality studies are needed to verify these findings and provide impactful reviews.
