Blood Pressure Control in Adolescents With CKD and Risk of Kidney Failure in Young Adulthood.
Article in Kidney medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Rationale & Objective: Understanding risk factors for chronic kidney disease (CKD) progression during adolescence is essential to improve outcomes for these individuals as adults. The objective of the present study was to retrospectively analyze electronic health records of children with CKD to understand the effect of cumulative systolic blood pressure (SBP) load during adolescence on time to kidney replacement therapy (KRT) or death during young adulthood. Study Design: Retrospective cohort study. Setting & Participants: Adolescents with CKD were enrolled from 14 academic medical centers in the Preserving Kidney Function in Children with Chronic Kidney Disease (PRESERVE) study. Individuals aged between 1 and less than 18 years with 2 or more estimated glomerular filtration rate measurements between 30 and <90 mL/min/1.73 m Exposure: Cumulative SBP load was defined using area under and above the SBP curve (ie, time and magnitude) and time-only approaches using the 50th, 75th, and 90th SBP percentiles. Outcomes: Time to KRT (long-term dialysis initiation or kidney transplantation) or death were ascertained via linkage with the US Renal Data System. Analytical Approach: Cox proportional hazards models were used to investigate the relationship between blood pressure (BP) control and the composite of KRT or death. Results: The cohort included 2,585 individuals with a median follow-up of 7.45 years (IQR, 6.05-9.20), among whom 4.6% (n = 118) met the KRT or death outcome between ages 18 and 30 years. In an adjusted Cox model, each unit increase (percentile point × time) in cumulative SBP load >90th percentile was associated with 1.36 (95% CI, 1.17-1.58) times higher hazard of KRT or death at age 18-19 years. Control of SBP to <90th percentile for 25%, 50%, and 100% of time between ages 14 and 18 years was associated with a 47%, 72%, and 92% risk reduction of KRT or death at age 18-19 years compared with no SBP control. Limitations: Misclassification of BP control related to white coat or masked hypertension. Adherence to prescribed antihypertensive medications was not assessed. Conclusions: Worse SBP control during adolescence was associated with a markedly increased risk of kidney failure in young adulthood. Cumulative SBP load derived from electronic health record data can inform risk of adverse long-term kidney outcomes.
