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
backgroundTransurethral resection of the prostate (TURP) remains the standard surgical treatment for benign prostatic hyperplasia (BPH), whereas laser-based procedures have increasingly been adopted as alternatives because of their potential advantages in hemostasis and postoperative recovery. This study compared coagulation depth, perioperative outcomes, postoperative complications, and short-term functional outcomes between 450-nm blue laser vaporization of the prostate (BVP) and TURP.
methodsThis retrospective single-center study included 260 patients with BPH who underwent either TURP (n = 110) or BVP (n = 150). Coagulation depth was compared between the two procedures using an ex vivo porcine kidney specimen experiment. Baseline characteristics, perioperative variables, intraoperative and postoperative complications, and postoperative functional outcomes at 1, 3, and 6 months were analyzed.
resultsBVP produced a significantly shallower coagulation depth than TURP. Baseline demographic and clinical characteristics were generally comparable between the two groups, although BMI and baseline QoL differed slightly. Compared with TURP, BVP was associated with a shorter operative time, earlier catheter removal, and a shorter hospital stay. Intraoperative complications were uncommon in both groups, and several postoperative complications were numerically less frequent in the BVP group. Both procedures resulted in substantial postoperative improvement in Qmax, PVR, IPSS, and QoL. In adjusted repeated-measures mixed-effects analyses, BVP showed greater improvement in Qmax and IPSS across follow-up and greater PVR reduction at 3 and 6 months, whereas QoL improved over time without a significant overall group effect.
conclusionsCompared with TURP, 450-nm BVP was associated with a shallower coagulation depth, more favorable perioperative recovery, and comparable short-term functional outcomes in patients with BPH. These findings support BVP as a feasible and promising transurethral alternative for the surgical management of BPH. The reduced coagulation depth observed after BVP may also have implications for postoperative inflammatory recovery and warrants further investigation.
