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

purposeBladder neck stenosis (BNS) is a long-term complication of surgical procedures for benign prostatic hyperplasia (BPH). We performed a systematic literature review and a meta-analysis of the incidence of BNS after transurethral procedures for BPH.

methodsWe performed a systemic literature review using MEDLINE, EMBASE, and Cochrane Central Controlled Register of Trials. We accepted only randomized trials comparing transurethral resection of the prostate (TURP) vs. other transurethral surgery for BPH that were grouped in Ablation vs. Enucleation modalities. The incidences of BNS were pooled using the Cochran-Mantel-Haenszel Method with the random effect model and expressed as Risk Ratios, 95% Confidence Intervals, and p values. Study heterogeneity was assessed utilizing the I

results72 studies were identified for meta-analysis, 46 comparing TURP vs. Ablation and 26 TURP vs. Enucleation. The pooled incidence of BNS was 1.3% after TURP, 0.66% after enucleation and 1.2% after Ablation. The incidence of BNS was higher after TURP than after Enucleation but the difference was not statistically significant (RR 1.75 95% CI 0.81-3.79, p = 0.16). There was no significant heterogeneity among the studies (I

conclusionOur study showed no difference in the rate of BNS incidence among randomized trials comparing TURP vs. Ablation vs. Enucleation and can be used as a reference to counsel patients undergoing BPH surgery.
