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
objectiveThis study aimed to evaluate first-time trial without catheter (TWOC) outcomes and postoperative urinary retention rates during short-term follow-up at three to six months in men with long-term catheterisation (LTC) or intermittent self-catheterisation (ISC) undergoing GreenLight laser photoselective vaporisation of the prostate (GLL.PVP).
methodsThis retrospective observational study included 20 consecutive men with benign prostatic hyperplasia (BPH) who were dependent on LTC or ISC and underwent GLL.PVP between May 2023 and July 2024 at a tertiary centre in the United Kingdom. During this period, 50 GLL.PVP procedures were performed, and these 20 cases represented all eligible catheter-dependent patients who met the inclusion criteria. Data were collected from clinical health records, including postoperative documentation, lower urinary tract symptoms (LUTS) clinic notes, TWOC clinic assessments, and emergency department presentations with urinary retention. Parameters analysed included patient age, prostate volume, catheter status, high-risk factors, and objective voiding parameters such as post-void residual urine volume (PVR) and maximum urinary flow rate (Qmax). The primary endpoint was first-time TWOC success, and the secondary endpoint was catheter-free status at three to six months.
resultsThe mean patient age was 72.8 ± 8.6 years, and the mean prostate volume was 72.5 ± 36.3 mL. Prior to surgery, 18 patients (90%) were managed with LTC and two (10%) with ISC. Nine patients (45%) were identified as high-risk due to anticoagulation therapy, prostate volume greater than 100 mL, or recurrent urinary retention. First-time TWOC was successful in 15 patients (75%), while five patients (25%) failed. At three to six months, 16 patients (80%) remained catheter-free, whereas four patients (20%) experienced recurrent urinary retention requiring re-catheterisation. Among patients who achieved catheter-free status postoperatively, the average PVR was 95 mL, and the average maximum urinary flow rate (Qmax) was 12.8 mL/s.
conclusionGLL.PVP appears to be a safe and feasible intervention for catheter-dependent men with BPH, demonstrating encouraging short-term outcomes with a high rate of successful first-time TWOC and sustained catheter-free status. These findings provide preliminary evidence supporting the potential role of GLL.PVP as a minimally invasive option for restoring spontaneous voiding in men with chronic catheter dependence.
