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

backgroundSlower chronic kidney disease (CKD) progression allows more time for transplant preparation. Whether differences in CKD progression by race/ethnicity associate with preemptive or living donor transplantation in youth has not been well studied.

methodsWe examined the association between time spent with low eGFR (between 10-30 mL/min/1.73 m

resultsAmong 333 youth with CKD (median age 11 years [IQR 7,14]), median time spent with low eGFR was 28.8 months. 77% were preemptively waitlisted, and 45% received preemptive transplantation (56% of White and 24% of Black youth). Black (vs. White) youth had shorter time with low eGFR (-6.5 months; 95% CI -11.5, -1.4). Time with low eGFR did not differ across other groups. Findings were similar using the U25 equation. Every additional year spent with low eGFR was associated with higher odds of preemptive (OR 1.45; 95% CI 1.24-1.70) and living donor transplantation (OR 1.42; 95% CI 1.21-1.67), but not preemptive waitlisting (OR 0.96; 95% CI 0.83-1.11) in unadjusted analyses.

conclusionsLonger time spent with low eGFR is associated with greater odds of preemptive and living donor transplantation. Earlier transplant referral for all children, especially Black youth, may help improve access to preemptive and living donor transplantation.
