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
Penile shortening is a recognized but neglected side effect of prostate cancer treatment. In this study we explore the effect of maximal urethral length preservation (MULP) technique on penile length preservation after robot assisted laparoscopic prostatectomy (RALP). In an IRB approved study, we prospectively evaluated the stretched flaccid penile length (SFPL) pre and post RALP in subjects with a diagnosis of prostate cancer. The multiparametric MRI (MP-MRI) was utilized for surgical planning if available preoperatively. Repeated measures t-test, linear regression and 2-way ANOVA analyses were performed. A total of 35 subjects underwent RALP. Mean age was 65.8 yr (SD: 5.9), preoperative SFPL was 15.57 cm (SD: 1.66) and postoperative SFPL was 15.41 cm (SD: 1.61) p = 0.68. No change in the postoperative SFPL was recorded among 27 subjects (77.1%) while 5 subjects (14.3%) had 0.5 cm shortening, and 3 subjects (8.6%) had 1 cm shortening. Pathologic stage, preoperative MP-MRI and body mass index (BMI) were significant predictors of postoperative SFPL on linear regression analysis, p = 0.001. Among 26 subjects with pathologic stage 2 disease, no statistical difference was seen in repeated measures t-test between pre and postoperative SFPL, 15.36 vs 15.3 cm, p = 0.08. All subjects were continent by 6 months postoperatively, with no complications. We demonstrate that incorporating MULP technique and preoperative MP-MRI preserves SFPL in subjects undergoing a RALP.
