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 investigate the role of combined periprostatic nerve block (PNB) and intrarectal local anesthesia with heated lidocaine gel (ILAHL) in reducing pain during transrectal ultrasound (TRUS)-guided prostate biopsy, compared with PNB alone. MATERIALS AND

methodsWe performed a prospective randomized trial with 140 participants who underwent systematic TRUS-guided, 12-core prostate biopsy from July 2021 to June 2022. These participants were divided into two groups. Before prostate biopsy, group 1 (n=70) received PNB and group 2 (n=70) received PNB combined intrarectal local anesthesia with 20 mL of heated (40℃) 2% lidocaine gel. The primary outcome was pain score on a 0-10 visual analogue scale (VAS) at four time points (VAS A: during local anesthesia procedure, VAS B: during probe insertion, VAS C: during biopsy procedure, VAS D: 30 minutes after biopsy). The secondary outcome included adverse events during and after the procedure.

resultsMean pain scores were significantly lower in group 2 than in group 1 at VAS A (2.53 vs. 1.60, p=0.001) and VAS B (2.47 vs. 1.49, p<0.001). The mean VAS C pain score in group 2 was significantly less than in group 1 (3.07 vs. 2.20, p=0.001), while there was no significant difference in the mean VAS D pain score between two groups (1.06 vs. 0.89, p=0.318). There were no significant differences in the occurrence of complications in both groups.

conclusionsThe combination of PNB and ILAHL provides more effective pain control than PNB alone without increase of complication rates in patients undergoing TRUS-guided prostate biopsy.
