The role of intravesical prostatic protrusion in the evaluation of overactive bladder in male patients with LUTS.

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.
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 evaluate the association of intravesical prostatic protrusion (IPP) and overactive bladder (OAB) in male patients with lower urinary tract symptoms (LUTS). IPP has been suggested to correlate with storage symptoms in addition to bladder outlet obstruction.
methodsThis was an open-labeled, single-center, prospective study involving 128 men older than 40 years presenting with LUTS. We analyzed the relationship of IPP with age, prostate volume, uroflowmetry, post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS), urgency severity scale (USS), and OAB symptom score (OABSS). The patients with an urgency score of ≥ 2 (OABSS question 2) and sum score of ≥ 3 were considered to have OAB. IPP was measured in the mid-sagittal section using transrectal ultrasound. The degree of IPP was classified as grade 1 (≤ 5 mm), grade 2 (> 5-10 mm), and grade 3 (> 10 mm).
resultsThe mean age of the patients was 64.9 ± 9.2 years, and 101 patients were diagnosed with OAB (79%). Mean IPPs were 2.4 ± 1.4 mm (grade 1, n = 77), 7.6 ± 1.4 mm (grade 2, n = 27), and 14.8 ± 4.4 mm (grade 3, n = 24). IPP was positively correlated with age, prostate size, PSA, PVR, and OABSS nocturia subscore, but not correlated with the presence or severity of OAB. Areas under the receiver-operating characteristic (ROC) curves for the diagnosis of OAB were 0.807 and 0.604 for IPSS-storage subscore and IPP, respectively.
conclusionIPP is not a good predictor of OAB in men presenting with LUTS. However, grade 3 IPP indicates higher frequency of nocturia.
