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
purposeTo evaluate whether repeated prostate-specific antigen (PSA) testing influences treatment patterns and healthcare costs for prostate cancer (PCa). MATERIALS AND
methodsWe analyzed a nationwide insurance cohort of men newly registered with PCa from 2010 to 2020. Patients were classified as PSA-tested (≥3 tests across ≥2 years before registration) or PSA non-tested (first PSA test within 3 months before registration). We compared the initial and subsequent treatment patterns between localized and systemic therapies, and per-patient medical expenditures by treatment modality. The analyses focused on 2016 to 2020, when government-set prices stabilized. Primary endpoints were cumulative medical costs and downstream medical utilization patterns.
resultsOf the 166,848 men, 26.7% were PSA-tested, 42.2% were non-tested, and 31.1% were undetermined. Localized therapy was more frequent after repeated testing: surgery, 45.6% versus 33.8% (p<0.001); radiotherapy, 17.0% versus 14.9% (p<0.001); and focal therapy, 0.8% versus 0.3% (p<0.001). Systemic therapy predominated without prior testing: hormone therapy, 59.7% versus 42.3% (p<0.001), chemotherapy, 2.7% versus 1.0% (p<0.001), and androgen receptor-targeted agents, 1.4% versus 0.5% (p<0.001). For localized modalities delivered during 2016 to 2020, the per-patient costs of non-robotic surgery and radiation therapy were comparable between the groups. In contrast, expenditures for hormone therapy and androgen receptor-targeted agents were significantly higher in the PSA non-tested group, primarily reflecting a longer treatment duration rather than higher monthly spending.
conclusionsOnce national prices stabilized, repeated PSA testing was associated with greater use of localized therapy and lower cumulative spending on prolonged systemic treatment without increasing the costs for localized modalities.
