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

backgroundWe hypothesized that prostatic anatomical factors may affect the progression of benign prostatic hyperplasia (BPH) and analyzed whether prostatic anatomical factors could be predictive of the risk of surgery. MATERIALS AND

methodsFrom February to October 2014, 679 men older than 40 years who had lower urinary tract symptoms and enlarged prostates were enrolled from five medical centers. Patients' medical characteristics, serum prostate-specific antigen levels, transrectal ultrasound (TRUS) results, and uroflowmetry were analyzed. Using TRUS in all patients, the total prostate volume, transitional zone volume, prostatic urethral length, transitional zone urethral length, intravesical prostatic protrusion, and prostatic urethral angle were measured. Logistic regression analysis was used to determine factors associated with the risk of surgery. Receiver operating characteristic curves were used to determine cutoff values for significant variables.

resultsOf 679 patients, 37 (5.4%) underwent BPH-related surgery. Prostatic urethral length and transitional zone urethral length were independently associated with the risk of surgery. Age, serum prostate-specific antigen levels, peak flow rate, postvoid residual urine, and other anatomical factors determined by TRUS were not statistically significant with respect to the risk of surgery. Using receiver operating characteristic curve-based predictions, the best cutoff values for prostatic and transitional zone urethral length were 4.53 cm (sensitivity: 83.3%, specificity: 61.6%) and 3.35 cm (sensitivity: 83.3%, specificity: 77.9%), respectively.

conclusionsThis study showed that patients with BPH with longer prostatic and transitional zone urethral lengths had a higher risk of surgery. Prostatic and transitional zone urethral length may be useful predictive factors for medical treatment failure in patients with BPH.
