Prostate cancer: diagnostic yield of modified transrectal ultrasound-guided twelve-core combined biopsy (targeted plus systematic biopsies) using prebiopsy magnetic resonance imaging.

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
purposeThis study aimed to analyze the diagnostic yield of modified transrectal ultrasound (TRUS)-guided 12-core combined biopsy (CB) using prebiopsy magnetic resonance imaging (MRI) for detecting clinically significant prostate cancer (csPCa).
methodsThis retrospective study included 130 consecutive patients who underwent modified TRUS-guided 12-core CB using cognitive fusion for lesions of Prostate Imaging-Reporting and Data System (PI-RADS) category ≥ 3. The 12-core CB comprised 3-6-core targeted biopsy (TB) and systematic biopsy (SB). For SB, tissue sampling in TB regions was omitted, and 3-core sampling (i.e., apex, mid, and base) in the contralateral peripheral zone of TB was mandatory. csPCa was defined as International Society of Urological Pathology (ISUP) grade ≥ 2 cancer. The per-patient cancer detection rates (CDRs) according to biopsy type or PI-RADS category were investigated.
resultsThe CDRs of TB, SB, and CB for csPCa were 47.7% (62/130 patients), 29.2% (38/130), and 52.3% (68/130), respectively. For csPCa, the CDRs of TB and CB according to PI-RADS categories of 3, 4, or 5 were 25.0% (8/32) and 31.3% (10/32), 41.2% (28/68) and 45.6% (31/68), or 86.7% (26/30) and 90.0% (27/30), respectively. In 6 (4.6%) patients, csPCa was detected only by SB. In 18 (13.8%) patients, SB detected PCa of a higher ISUP grade than TB. In 11 (8.5%) patients, SB detected csPCa at contralateral peripheral zone of TB.
conclusionModified TRUS-guided 12-core CB using prebiopsy MRI seems to be feasible. It may reduce total biopsy cores in patients who are suitable for CB based on prebiopsy MRI findings.
