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
introductionProstate cancer is one of the most commonly encountered urologic malignancy. Biopsy samples may be attained using TPPB-VY or TRPB; both of the approaches are relatively comparable in terms of accuracy. Transperineal Access System revolutionizes the methodology for obtaining prostate biopsies. But in Indonesia this device is not available and expensive, we developed VY probe mounted needle guide device. The study was aimed to compare cancer detection rate and rates of cancer detection in Grade Groups (GG) between these two approaches, particularly in prostate cancer patients.
methodsA cross-sectional study with retrospective data from patients diagnosed with prostate cancer in Hasan Sadikin General Hospital in 2019 - 2020 was performed. Ethical approval of this study was sought from the hospital authorities (IRB number: LB.02.01/X.6.5/ 55/2020). The patient was included to the study if PSA ≥ 4 ng/ml, DRE results suggestive of prostate cancer. The diagnostic accuracy of both approaches was compared using histopathological analysis.
resultsThere were 44 patients included in the study; 22 patients had received TRPB and 22 patients had TPPB-VY. Higher degree of cancer detection rates was found in patients receiving TPPB-VY. Patient with Prostatic adenocarcinoma were all found having hypoechoic lesion in TPPB-VY. On the other hand, half of the patient with Prostatic adenocarcinoma shown having no lesion in TRPB. Prostate cancer with hypoechoic lesion can be detected better by TPPB-VY than TRPB. Cancer detection rates on TPPB-VY were significantly higher than on TRPB for each grade group.
conclusionAmong patient with hypoechoic lesions, TPPB-VY led to more detectionof prostate cancer, it provides detection of all grade groups and high-grade prostate cancer, this showed a non-inferior TPPB-VY compared to TRPB. TPPB-VY should be considered as an option for all men in whom a prostate biopsy is indicated.
