Comparison of intrarectal heated lidocaine gel and periprostatic nerve block for pain control in transrectal ultrasound-guided prostate biopsy: A randomized controlled non-inferiority trial.
Article in Prostate international, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Background: To investigate whether intrarectal local anesthesia with heated lidocaine gel (IRLAH) is non-inferior to periprostatic nerve block (PNB) for reducing pain in patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy. Methods: We performed a randomized controlled non-inferiority trial with 100 participants who underwent systematic TRUS-guided, 12-core prostate biopsy from August 2019 to July 2020. These participants were randomly assigned to a group receiving intrarectal local anesthesia with 20 mL of heated (40°C) 2% lidocaine gel (n = 50) or PNB (n = 50). The primary outcome was a pain score on a 0-10 visual analogue scale (VAS) at four time points with the non-inferiority margin of 1; VAS-1: during local anesthesia application; VAS-2: during probe insertion; VAS-3: during biopsy; VAS-4: 30 minutes after the procedure. The secondary outcome included complications during and after the procedure. Results: The IRLAH group (0.1) met non-inferiority as well as superiority criteria for mean VAS-1 score vs. the PNB group (2.33) ( Conclusion: IRLAH is a noninvasive and non-inferior alternative to PNB for pain control in TRUS-guided prostate biopsy without increased risk of complications.
