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

objectiveTransurethral resection of the prostate (TURP) is a common procedure for the treatment of benign prostatic hyperplasia (BPH). Previous studies on the effect of 5-alpha reductase inhibitors on perioperative blood loss in TURP and microvessel density (MVD) in the prostate are equivocal. We evaluated whether pretreatment with finasteride for 2 weeks before surgery can reduce perioperative blood loss in TURP and MVD in the prostate. MATERIALS AND

methodsSixty-eight patients of BPH planned for TURP were randomized into two groups. The study group comprising 34 patients was treated with finasteride (5 mg/day) for 2 weeks and the placebo group comprising 34 patients received placebo for 2 weeks, before TURP. Blood loss was measured in terms of a reduction in the blood hemoglobin (Hb) and hematocrit (HCT) levels between preoperative values and 24 h after surgery. MVD was measured in the resected prostate tissue stained with anti-CD31 monoclonal antibody.

resultsThe reduction of Hb and HCT in the finasteride group was significantly lower than the reduction in the placebo group (

conclusionsOur study suggests a clear advantage of the preoperative use of finasteride for 2 weeks by reducing the perioperative blood loss in TURP in patients with BPH. While there is a significant reduction in MVD in the prostate on treatment with finasteride, it is not clear that this is the mechanism of reduction in blood loss in TURP.
