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

purposeTo establish age-stratified normal values for prostate volume, serum total prostate-specific antigen (PSA) concentration, maximum urinary flow rate (Q (max)), micturition and postvoid residual urine volumes, IPSS, and quality of life. These community-derived values of healthy older men are necessary to correctly judge patients with lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH).

methodsAnalysis of LUTS/BPH-related determinants in community-dwelling men in the city of Herne, Germany after exclusion of subgroups with co-morbidities or co-medications with possible influence on the key items.

resultsThe analysis is based on 1,763 participants. In these men aged 50-80 years, mean total prostate volume continuously increased from 24 to 38 cc and mean PSA concentration from 1.1 to 2.5 ng/ml. PSA concentration in men with a prostate volume <25 cc also showed a continuous increase with aging, starting at 0.8 in the youngest and ending at 1.9 ng/ml in the oldest age group. Mean Q (max) of free uroflowmetry (from 22.1 to 13.7 ml/s) and mean micturition volume (from 329 to 193 cc) showed a continuous decrease that was dependent on prostate size. Mean postvoid residual urine was nearly unchanged over the age groups at approximately 20-30 cc. Although IPSS increased continuously with aging (from 4 to 7), QoL remained unchanged at 2 over the age groups. Prostate size had a minor impact on IPSS.

conclusionsNormal values for investigated LUTS/BPH-related determinants and the influence of aging hereon should serve as references during the assessment of Caucasian patients in Europe.
