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

introductionBenign prostatic hyperplasia (BPH) includes epithelial, stromal and mixed hyperplasia, but their specific contributions to voiding symptoms and prostate volume (PV) are unknown. Here, we examined relationships of symptoms and PV with stromal and epithelial markers in patients undergoing laser enucleation for BPH.

methodsTissues were obtained from holmium or thulium laser enucleation of the prostate (n = 146 patients). Expressions of the smooth muscle marker calponin-1 (CNN1) and the glandular-epithelial cell marker keratin-19 (KRT19) were assessed by RT-PCR and Western blot, and analyzed for correlation with international prostate symptom score (IPSS), maximum urinary flow rate (Qmax), and PV.

resultsThe ratio of CNN1/KRT19 mRNA correlated positively with Qmax (r = 0.3809, p = 0.0263), and by trend negatively with IPSS (r = -0.2161, p = 0.0944). Accordingly, the IPSS increased with keratin protein expression (r = 0.4244, p = 0.0307), while the Qmax tended to correlate negatively with keratin expression (r = -0.2058, p = 0.4999). PV correlated negatively with CNN1 mRNA expression (r = -0.205, p = 0.0405). The inverse correlation of CNN1 with PV persisted in patients without catheterization (r = -0.2568, p = 0.0457), but was lacking in catheterized patients after separated analyses.

conclusionsVoiding symptoms in patients undergoing laser enucleation for BPH aggravate with increasing keratin content. Symptoms in patients needing surgery for BPH depend rather on glandular-epithelial hyperplasia, but not on stromal hyperplasia, what might explain why these patients are refractory to treatment with α1-blockers.
