The Effects of the Blood-Based S2,3PSA% Test on Prostate Cancer Screening: A Novel Approach to Reduce the Need for MRI and Unnecessary Biopsies.

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
objectiveProstate-specific antigen (PSA)-based screening has reduced prostate cancer (PCa) mortality but is associated with overdiagnosis/overtreatment. We developed and evaluated a blood-based S2,3PSA% test to address the limitations of PSA-based screening for PCa.
methodsThis retrospective study included men aged ≤ 75 years who underwent opportunistic PSA and S2,3PSA% screening between April 2022 and March 2023. Secondary screening was recommended for participants with PSA ≥ 2.0 ng/mL and S2,3PSA% ≥ 38.0%, or PSA ≥ 4.0 ng/mL. The primary outcome was the reduction in MRI utilization based on an S2,3PSA% cutoff of ≥ 38.0%. Secondary outcomes included the PCa detection rate, as well as reductions in prostate biopsies and medical costs.
resultsAmong 808 participants who underwent PSA and S2,3PSA% screening, 190 met the criteria for secondary screening. Of these, 72 underwent further evaluation, including MRI in 65 participants. MRI findings excluded 22 (33.8%) participants from requiring prostate biopsy. Ultimately, 25 participants underwent prostate biopsy, and PCa was diagnosed in 17 (68.0%), including 12 with clinically significant PCa. The combined use of PSA, S2,3PSA%, and MRI resulted in a 44% reduction in MRI use, a 63% reduction in unnecessary biopsies, and a 72% reduction in medical costs. Study limitations include the small sample size and lack of evaluation of participants with negative S2,3PSA% or MRI findings.
conclusionsS2,3PSA% screening may have potential as a tool to reduce the need for MRI, unnecessary biopsies, and medical costs.
