Association between Nocturnal Frequency and Erectile Function in Eugonadal Men with Benign Prostatic Obstruction: A Cross Sectional Study.

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
purposeWe aimed to evaluate the association between nocturnal frequency and erectile dysfunction in patients with benign prostatic obstruction. MATERIALS AND
methodsTo evaluate the association, we simultaneous evaluated urodynamic study, prostate ultrasound, nocturnal tumescence test (nocturnal penile tumescence) for sleep-related erection (SRE) and two questionnaires, international prostate symptom score (IPSS) and 5-item version of the international index of erectile function (IIEF-5). Patients with hypogonadism or nocturnal polyuria were excluded.
resultsForty-six patients were registered over 4 years. The mean age, prostate size, IPSS score, and IIEF-5 score were 67.65±5.51 years, 65.10±22.12 mL, 24.67±7.89, and 9.50±7.01, respectively. Among the IPSS subscores, nocturia was most significantly related to the total IIEF-5 score (p<0.001). More severe nocturia was associated with less frequent SRE (p=0.003) and shorter total duration of SRE (p=0.002), which in turn elucidated that nocturia was significantly related to the total amount of rigidity signals (rigidity activity unit, RAU) or tumescence signals (tumescence activity unit, TAU). Among objective urodynamic parameters, bladder compliance also correlated to RAU and TAU. Individual subjective erectile function (IIEF-5) was significantly related to both RAU and TAU.
conclusionsSleep fragmentation due to benign prostate obstruction related nocturnal frequency caused by reduced bladder compliance could decrease the frequency and duration of SRE, which decreases the total amount of SRE and reflects the patient's relevant erectile function.
