Impact of Sarcopenia on Erectile Function after Nerve-Sparing Robot-Assisted Radical Prostatectomy.
Article in The world journal of men's health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 determine the impact of sarcopenia on erectile functional outcomes after a nerve-sparing (NS) robot-assisted radical prostatectomy (RARP) using patient-reported validated questionnaires. MATERIALS AND
methodsIn this retrospective study, RARP was performed on 841 patients at Okayama University Hospital, of which 132 underwent NS RARP. Erectile functional outcomes were assessed using the 5-item version of the International Index of Erectile Function (IIEF-5) and the Expanded Prostate Cancer Index Composite before and 1, 3, 6, and 12 months after surgery. Automated measurement of skeletal muscle at L3 was achieved using volume analyzer software and normalizing for height (cm²/m²) to calculate skeletal muscle index (SMI). Patients who had an IIEF-5≤4 comprised the group with erectile dysfunction (ED), and those with an IIEF-5≤5 made up the non-ED group.
resultsThis study enrolled 95 patients of median age 65 years with a preoperative IIEF-5 of 16. There were no significant differences between patients with and without sarcopenia among those with preoperative IIEF-5. Postoperatively, in the ED group, SMI and preoperative IIEF-5 were significantly lower than in the non-ED group. Multiple linear regression analysis revealed that (1) both SMI and preoperative IIEF-5 were independent predictors of ED, and (2) sarcopenia and preoperative IIEF-5 were predictors of ED at 12 months after NS RARP.
conclusionsPatients with sarcopenia can have worse erectile functional outcomes after NS RARP. Sarcopenia and a lower preoperative IIEF-5 score may be predictive of postoperative ED.
