Uncovering a Long-term Graft Survival Advantage Afforded by Infant Renal Transplants-An Organ Procurement and Transplantation Network Database Analysis.

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
backgroundRenal transplants (Tx) are performed infrequently in infants, due to concerns related to poor outcomes. The aim of our study was to compare graft failure rates in infant (<1 y) renal Tx recipients compared with older children.
methodsRetrospective cohort study of pediatric renal Tx recipients from 2000 to 2015, using the Organ Procurement and Transplant Network database. A log-linear event history regression model for time to graft failure, adjusting for age group and important confounders, was used to estimate post-Tx graft failure probabilities.
resultsIn 2696 Tx followed for a median of 6.1 y, 704 failures were observed. Significant predictors of graft failure were year of Tx (for each year after 2000, rates were 8.6% lower), Black race-ethnicity (63% higher compared with Whites), and number of HLA matches. For infants (n = 27), estimated graft failure percentage (95% confidence interval) within the first 1-, 2-, and 5-y post-Tx were 10.4 (0.1-21.1), 11.9 (1.2-22.6), and 16.4 (4.9-27.9). For the 1- to 11-y-olds (n = 1429), these were 3.8 (3.0-4.6), 6.3 (5.4-7.3), and 13.6 (12.2-15.0), respectively, and for the 12+ y olds (n = 1240), they were 3.8 (3.1-4.5), 8.1 (7.2-9.0), and 19.9 (18.1-21.7), respectively (
conclusionsInfant renal Tx recipients experience a higher graft failure rate in the first year, compared with older cohorts, but over longer intervals, cumulative failure rates are comparable or even lower. To minimize early graft losses such Tx should be performed in experienced centers.
