Evaluation of electrophysiological changes after radical prostatectomy and their relationship with erectile function recovery.

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
Erectile dysfunction (ED) is a common complication of radical prostatectomy (RP), mostly due to cavernous nerve (CN) injury. Despite improved surgical techniques and tools, ED rates are still high. Electrophysiological studies help to understand the functional effects of RP on CN and cavernous smooth muscles. The aim of this study is to evaluate the clinical reflection of changes on corpus cavernosum electromyography (CC-EMG) parameters caused by RP. A total of 44 patients were included in this prospective cohort study who underwent RP. The patients were divided into three groups based on nerve-sparing status: bilateral nerve-sparing (Group A) (n = 21), unilateral nerve-sparing (Group B) (n = 12), and non-nerve-sparing (Group C) (n = 11). All patients underwent CC-EMG one month before the operation and at the postoperative third month and were administered the International Index of Erectile Function (IIEF)-5 one month before the operation and at the postoperative third and 12th months. The postoperative third-month CC-EMG showed that the degree of cavernous smooth muscle relaxation in Group A was significantly higher than in Group B and Group C (p = 0.010 and p = 0.032, respectively). In the regression analysis, it was determined that patients with a postoperative IIEF-5 score of 12 or higher at the 12th month had a significantly greater degree of relaxation on the postoperative third-month CC-EMG (p = 0.034). In conclusion, a greater relaxation degree on postoperative third-month CC-EMG correlates with better long-term recovery of erectile function in patients who underwent RP.
