A comparative analysis of the starting modality of kidney replacement therapy amongst UK children and young adults and the association with all-cause mortality.

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
backgroundFew studies have compared the long-term survival of children by their first modality of kidney replacement therapy (KRT). This study aimed to compare the mortality outcomes of children starting dialysis as their first KRT modality to those who received a pre-emptive kidney transplant (PKT).
methodsHistorical cohort analyses of UK children starting KRT between 1997-2020 were undertaken, using data from the UK Renal Registry linked to Hospital Episodes Statistics. Crude and multivariable Cox proportional hazards regression analyses were performed to compare mortality amongst children with complete records who received (i) haemodialysis (HD) and (ii) peritoneal dialysis (PD) for ≥ 3 months with those receiving PKT, stratified by the time-period of KRT initiation. Mortality estimates were adjusted for sociodemographic, time-period, primary kidney disease and comorbidity-related covariates.
results242 deaths were recorded amongst 2440 children included in complete-case analyses. Adjusted mortality amongst children was highest (HR 3.70, 95% CI: 1.41-9.74), when compared to PKT) for those starting HD in 1997-2008. Evidence for a difference in mortality amongst children receiving HD (compared to PKT) was weak in later time-periods (2009-14, 2015-20). Mortality did not differ amongst children receiving PD first compared to those who had been pre-emptively transplanted.
conclusionsWhilst adjusted mortality was highest for children starting HD at KRT onset in the earliest time-period, there were no differences in long-term survival amongst those starting dialysis (HD or PD) to those pre-emptively transplanted in more recent years.
