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

Background: An underappreciated complication of laparoscopic nephrectomy in male living kidney donors is testicular pain, swelling, and hydrocele development. A recent cohort study in Ontario, Canada, found that male donors had a higher rate of hydrocelectomy (7.7 vs. 0.1 events/1000 person-years) and scrotal ultrasounds (25.6 vs. 6.9 events/1000 person-years) than nondonors, when followed for a median of 9 years. Objective: To conduct a replication study in Alberta, Canada, examining the long-term risk of hydrocelectomy after laparoscopic living donor nephrectomy, comparing male donors to nondonors from the general population matched on baseline health indicators. Design: Population-based matched cohort study using linked healthcare databases. Setting: Alberta, Canada (April 1, 2002, to March 31, 2021). Patients: We matched 115 male kidney donors who underwent a laparoscopic nephrectomy with 1150 nondonors. The matching characteristics were age at cohort entry, date of cohort entry, rural residence, income, prior vasectomy, and prior inguinal hernia repair. Measure: ments: The primary outcome was a hydrocelectomy, and the secondary outcome was receipt of a scrotal ultrasound. Methods: Males were followed for a median of eight years, with a maximum follow-up of 19 years. Results: The rate of hydrocelectomy was higher in donors than in nondonors (3 of 115 [2.6%] vs. 1 of 1150 [0.1%]; 3.3 vs. 0.1 events/1000 person-years; Limitations: A low event rate impeded a precise estimation of the risk of hydrocelectomy attributable to donation. Conclusions: In this population-based cohort study from Alberta, Canada, rates of hydrocelectomy and receipt of a scrotal ultrasound were significantly higher in males who underwent laparoscopic living donor nephrectomy than in male nondonors matched for age and other factors. Males considering living kidney donation should be informed of the risk of developing a symptomatic ipsilateral scrotal hydrocele in the years following laparoscopic nephrectomy.
