Detection of Significant Prostate Cancer According to Anatomical Areas of Sampling Cores Obtained with Transrectal Systematic 12-Core Biopsy.
Article in Current urology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo analyze the diagnostic performance of 12-core biopsy in detecting significant prostate cancer (PCa). PATIENTS AND
methodsThisstudy included 206 PCa patients who underwent transrectal 12-core biopsy followed by radical prostatectomy. Radical prostatectomy specimens were anatomically divided into 12 areas according to the sampling cores, and the existence of significant cancer, defined by a tumor volume > 0.5 ml, was investigated. The detection rate of significant cancer in each area was calculated as follows: the number of positive core biopsies/the number of areas containing significant cancer × 100.
resultsThe overall detection rate of significant cancer in all areas was 53.6%. The detection rate was significantly higher in the standard sextant cores than in the additional 6 cores in patients with prostate-specific antigen ≥ 10 ng/ml, clinical stage ≥ T2, or biopsy Gleason score ≥ 7, but not in those with prostate-specific antigen < 10 ng/ml, clinical stage T1c, or biopsy Gleason score ≤ 6.
conclusionsApproximately half of the significant cancers were not accurately detected, and the detection rates in biopsy cores other than the sextant cores appeared to be significantly lower in PCa patients with aggressive features.
