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

introductionProstate growth and androgenic alopecia are both under the influence of dihydrotestosterone. Dihydrotestosterone can make prostates larger and men balder. Therefore, we assessed the association of men suffering from lower urinary tract symptoms and androgenic alopecia. MATERIAL AND

methodsWe enrolled 177 subjects which underwent a Green Light Laser Vaporization Procedure of the prostate between 2006 and 2017. We identified two groups of males with different levels of androgenic alopecia, classified according to the Norwood-Hamilton scale, which we compared in this study. lower urinary tract symptoms were evaluated using the International Prostate Symptom Score questionnaire. Other parameters included demographics, urodynamics, prostate volume and prostate-specific antigen.

resultsMean patient age was 68 (47-87) years. Mean International Prostate Symptom Score was 20 (1-35). 59.3% of subjects were classified as bald using the Norwood-Hamilton scale (androgenic alopecia score). Mean prostate size (range) was 77.5 ml (21-245), mean Qmax was 9 ml/s (1-25), and mean PSA was 4.7 ng/ml (0.3-39). The androgenic alopecia score correlated with none of the other parameters. PSA and prostate volume correlated with the Schäfer obstruction classification. Qmax correlated with the Schäfer classification and International Prostate Symptom Score. International Prostate Symptom Score correlated with QoL. Schäfer classification correlated with PSA, prostate volume, Qmax and age.

conclusionsAs expected, various lower urinary tract symptoms parameters in our study correlated with each other. However, no correlation was found between the androgenic alopecia score and LUTS or prostate volume. This score cannot be used to estimate prostate size.
