1 · What the graph read from it

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.

2 · The registry

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

The purpose of this study is to assess the likelihood of detecting stage T1a and T1b cancer in transurethral prostatectomy specimens during the PSA era. Comparison was made of transurethral resection of prostate (TURP) cohorts in the pre-PSA era (1986-1987) and the PSA era (1994-2000), excluding patients with known PCa. A total of 228 men without a known history of prostate cancer underwent TURP during the pre-PSA era time frame and 501 underwent the procedure during the PSA era time frame. Malignancy diagnosed at the time of TURP decreased from 14.9 to 5.2% of patients in the pre-PSA and PSA eras, respectively. Stage T1a decreased from 4.4 to 2.4% and Stage T1b decreased from 10.5 to 2.8% of patients in the pre-PSA and PSA eras, respectively (P<0.001, Fisher's exact test). Prostate cancer newly identified during TURP has decreased significantly in the era of PSA screening in our study population, with the most significant drop being in clinically significant stage T1b. The decrease in TURP rates reduces the overall incidence of T1a/b cancer but cannot explain the lower risk of detecting previously unsuspected cancer at the time of any given TURP. Identification of many men with occult prostate cancer before TURP through screening and early detection is the most likely cause of this finding. These data suggest that men considering surgical or medical management of benign prostatic hyperplasia may be informed that it should be infrequent that men properly evaluated for prostate cancer will harbor clinically significant undetected malignancy.
