1 · What the graph read from it

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.

2 · The registry

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

backgroundErectile dysfunction (ED) is common in patients with end-stage renal disease (ESRD). Whether kidney transplantation can improve erectile function in patients with ESRD is still controversial. We conducted a meta-analysis on the relationship between kidney transplantation and erectile function.

methodsA literature search was conducted on PubMed, Embase, Cochrane Library, and Web of Science until May 31, 2019. Primary outcomes were ED prevalence and each domain score of the International Index of Erectile Function (IIEF) questionnaire. We used age-matched dialysis patients or patients before kidney transplantation as a control group and compared them to kidney transplant recipients.

resultsA total of 9 articles were finally enrolled in the study. Compared with the control group, the kidney transplantation group had a lower prevalence of ED (OR 0.49, 95% CI: 0.28-0.86) and higher domain scores for erectile function (SMD 0.53, 95% CI: 0.12-0.94) and sexual desire (SMD 1.19, 95% CI: 0.11-2.27). While there were no significant variations in domain scores for orgasmic function (SMD 0.27, 95% CI: -0.10-0.63), intercourse satisfaction (SMD 0.26, 95% CI: -0.10-0.61), and overall satisfaction (SMD 0.17, 95% CI: -0.21-0.56). Patients in the kidney transplantation group had higher serum testosterone (SMD 1.20, 95% CI: 0.86-1.54) and lower prolactin (SMD -1.46, 95% CI: -2.22 to -0.69) and luteinizing hormone (SMD -0.97, 95% CI: -1.39 to -0.55).

conclusionsKidney transplantation may be associated with improved erectile function in patients with ESRD. This may be attributable to the correction of endocrine hormone disorders in patients after kidney transplantation.
