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

backgroundThe etiology of benign prostatic hyperplasia (BPH) is not well understood, though recent literature suggests that the urinary tract microbiome may play a role. We aimed to examine the prostatic microbiome in BPH and its associations with patient characteristics.

methodsMen undergoing Holmium Laser Enucleation of the Prostate (HoLEP) were recruited if they were over 18 years old and had no history of prostate cancer, prostate surgery, or pelvic radiation. Exclusion criteria included positive preoperative urine culture, bladder stones, or catheter-dependence. Patient characteristics including age, prostate-specific antigen (PSA), American Urological Association symptom score (AUASS), and history of biopsy were recorded. Intraoperatively, prostate tissue was collected from each patient, as well as catheterized urine, urethral swabs, and swabs of the specimen container. Samples underwent DNA extraction, 16S sequencing, and analysis using R statistical software. Associations between bacterial taxonomic diversity and patient characteristics were quantified through Sparcc correlations.

resultsFifty patients were recruited. Mean age, PSA, prostate size, and AUASS were 67.8 years, 4.0 ng/mL, 108.6 g, and 19.4, respectively. After bioinformatic decontamination of prostate samples, alpha and beta diversity analyses indicated that microbiomes from the prostate, urethra, and urine were all distinct (p = 0.001); microbiota from the urine and urethra had higher similarity to each other than that of the prostate. Campylobacter, Caryophanaceae, Enterobacter, and Senegalimassilia positively correlated with prostate size or PSA.

conclusionsThe prostatic microbiome is unique and distinct from that of urine and urethra, with several known pathogens positively correlating with prostate size and PSA.
