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
introductionTransurethral resection of bladder tumour (TURBT) is one of the most commonly performed urologic procedures. Because of the shortcomings of conventional TURBT, the en-bloc resection concept was created.
aimTo analyse the influence of en-bloc technique on surgical and oncological outcomes of TURBT performed with electric current. MATERIAL AND
methodsThis non-randomized, prospective controlled multicentre study enrolled 427 consecutive patients undergoing TURBT performed by five experienced endourologists in five academic institutions. Choice of procedure was at the discretion of the surgeon. The vast majority of patients underwent monopolar resection. The en-bloc procedure was performed with Collin's knife or the classic resection loop. Study end-points were surgery, catheterization and hospitalization time, presence of muscularis propria (MP) in the specimen and 3-month recurrence-free survival (RFS).
resultsThe study included 427 (274 conventional TURBT vs. 153 en-bloc) patients with mean age of 69 years (range: 18-99). There were more cases with MP present in the specimen in the en-bloc group (91.3% vs. 75.5%; p < 0.001). Surgery and hospitalization times were statistically shorter in the en-bloc group (both p < 0.05). A borderline significant difference was noted when the number of residual tumours in reTURBTs was analysed, with fewer cases of residual tumour in the en-bloc group (p = 0.051). RFS at 3 months was higher in the en-bloc group (88.4% vs. 80.1%; p = 0.027). After propensity score matching, differences in MP presence, hospitalization time and 3-month RFS status remained statistically significant.
conclusionsWhen compared to conventional TURBT, en-bloc resection of bladder tumour is associated with higher percentage of MP presence in histopathological specimen, higher 3-month RFS and shorter hospitalization time.
