Prostate-Specific Antigen Modulatory Effect of a Fermented Soy Supplement for Patients with an Elevated Risk of Prostate Cancer: a Non-Randomized, Retrospective Observational Registration.
Article in Current urology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 7 papers.
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
objectiveTo investigate the efficacy of a 6-month fermented soy supplement (equol-containing), measured by prostate-specific antigen (PSA) stabilization or PSA decrease from baseline (PSA modulatory effect) in men with an elevated risk of prostate cancer (PCa), with a WHO performance 0-2 and a follow-up of 12 months.
methodsThe patient population consisted of men with an elevated risk of PCa and a prior negative prostate biopsy within 1 year from starting therapy. Serum PSA values were recorded at inclusion (iPSA), at 6 months (1PSA), and optionally at 12 months (2PSA). Statistical analysis was carried out using the Wilcoxon rank sum test (p < 0.05).
resultsIn total, 137 men used fermented soy for any prostatic reason. After inclusion criteria for an elevated risk of PCa and a prior negative prostate biopsy, we selected 58 patients. Among these, there was a significant PSA modulatory effect (iPSA-1PSA, p = 0.003). This modulatory effect was more strongly evident in the subgroup of patients with an elevated iPSA (≥ 4 ng/ml) (n = 33, iPSA-1PSA, p = 0.003, iPSA-2PSA, p = 0.002).
conclusionsWe demonstrated a significant PSA modulatory effect of a 6-month fermented soy supplement in men with an elevated risk of PCa and a prior negative prostate biopsy. This positive effect is currently being investigated in a prospective study. Further evaluation of the role of fermented soy supplements is warranted in a preventive and therapeutic setting of men at an elevated risk of PCa.
