1 · What the graph read from 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.

2 · The registry

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

backgroundTransurethral resection of bladder tumour (TURB) is the initial and crucial step in the management of non-muscle invasive bladder cancer (NMIBC), having both diagnostic and therapeutic role. For many years, the gold standard for TURB was monopolar TURB (mTURB), however, it is associated with several complications related to its technical details. To overcome limitations of mTURB, TURB using bipolar technology (bTURB) has been developed. So far, making unequivocal statement about definitive advantage of bTURB over mTURB was difficult. The aim of this study was to systematically evaluate and compare the efficacy and safety of bTURB with mTURB.

methodsA systematic search was conducted independently by two authors on the 4 electronic databases, including PubMed, Scopus, Embase and Cochrane Library, according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Nine comparative prospective studies with randomization (8 RCTs and 1 post-hoc analysis of RCT) were eligible to be included in this meta-analysis.

resultsAfter extraction, data were pooled to conduct the meta-analysis. The following outcomes were analysed: operation time, catheterization time, length of hospital stay, decrease in postoperative haemoglobin level, obturator nerve reflex rate, bladder perforation rate, transfusion rate, TUR syndrome rate, one year recurrence rate, failures of detrusor muscle detection. bTURB was associated with decreased operation and hospitalization time. There were no statistically significant differences between bTURB and mTURB in terms of catheterization time, decrease in haemoglobin level, postoperative complications rates, recurrence rates and pathologic outcomes.

conclusionsThis meta-analysis corroborates that bTURB shows significant advantage over mTURB in terms of operation and hospitalization time while other outcomes are comparable.
