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

purposeTo compare the efficacy, safety and operational efficiency of transperineal radiofrequency ablation (TPRFA) and single fiber transperineal laser ablation (TPLA) in patients with benign prostatic hyperplasia (BPH). MATERIALS AND

methodsPatients with moderate to severe lower urinary tract symptoms were included and divided into TPRFA and TPLA groups. Changes in International Prostate Symptom Score (IPSS), quality of life (QoL), prostate volume (PV), post-void residual (PVR), and peak urine flow rate (Qmax) at 6 and 12 months were analyzed and compared between the two groups. Postoperative complications, operation time, ablation time were compared between the two groups.

resultsThirty-six patients (20 TPRFA vs 16 TPLA) were analyzed. At 12 months, the between-group difference in change in IPSS, QoL, PV, Qmax and PVR from baseline was - 1.59 (95% CI: - 5.12 to 1.94, p = 0.37), 0.16 (95% CI: - 0.39 to 0.70, p = 0.57), - 5.00 (95% CI: - 10.41 to 0.41, p = 0.07), - 0.10 (95% CI: - 3.52 to 3.32, p = 0.95), - 6.40 (95% CI: - 93.30 to 81.09, p = 0.88). The TPRFA group had significantly shorter operation time and ablation time than the TPLA group (p < 0.001). Complication rates were similar in both groups (20% in TPRFA and 25% in TPLA, p = 0.740), mainly urinary retention.

conclusionBoth TPRFA and TPLA effectively improved lower urinary tract symptoms in BPH patients, with no significant statistical difference in therapeutic efficacy observed at 12 months post-procedure. TPRFA was associated with a shorter operation time and ablation time, which may make it a new option for BPH treatment. LEVEL OF EVIDENCE: Level 3b, Retrospective Cohort Study.
