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
backgroundMagnetic resonance imaging (MRI)/ultrasound targeted biopsy has frequently been used together with a 12-core systematic biopsy for prostate cancer screening in the past few years. However, the efficacy of targeted biopsy compared to systematic biopsy, as well as its clinical-histologic correlation, has been assessed by a limited number of studies and is further investigated in this study.
designWe collected 960 cases with both targeted and systematic prostate biopsies from 04/2019 to 04/2022 (Table 1). We compared cancer detection rates between targeted and systematic prostate biopsies in different grade groups. Correlations with the size of prostate lesions, prostate-specific antigen (PSA) level, and Prostate Imaging-Reporting and Data System (PI-RADS) scale were also analyzed for each of these biopsy methods.
resultsAmong the 960 men who underwent targeted biopsy with systematic biopsy, prostatic adenocarcinoma was diagnosed in 652 (67.9%) cases. 489 (50.9%) cases were diagnosed by targeted biopsy and 576 (60.0%) cases were diagnosed by systematic biopsy. In the 384 cases diagnosed negative by systematic biopsy, targeted biopsy identified cancer in 76 (8%) cases. Systematic biopsy was able to detect 163 cancer cases that were missed by targeted biopsy. Systematic biopsy detected more grade group 1 cancers compared to targeted biopsy. However, for higher grade cancers, the differences between the cancer detection rates of targeted biopsy and systematic biopsy became negligible. Targeted biopsy upgraded the grade group categorized by systematic biopsy in several cases (3.8%, 7.0%, 2.6%, 1.1% and 0.9% in Grade Groups 1, 2, 3, 4, and 5 respectively). Targeted biopsy was more likely to detect cancer in larger lesions (13.17 mm VS 11.41 mm, P=0.0056) and for higher PI-RADS scales (4.19 VS 3.68, P<0.0001). The cancers detected by targeted biopsy also had higher PSA levels (10.38 ng/ml VS 6.39 ng/ml, P=0.0026).
conclusionTargeted biopsy with systematic biopsy improved cancer detection rate compared to systematic biopsy alone. Targeted biopsy is not more sensitive for grade groups 1, 4, or 5 cancers but is as sensitive as systematic biopsy for detecting grade group 2 and 3 cancers. Targeted biopsy is more effective at detecting cancers when patients have larger lesions, higher PI-RADS scales, and higher PSA levels.
