Circadian blood pressure patterns in kidney transplant recipients assessed by ambulatory blood pressure monitoring.
Observational study in Pediatric nephrology (Berlin, Germany), 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
backgroundPost-kidney transplant arterial hypertension (HTN) is a very common complication that deteriorates grafts, shortens their lifespan, and involves an increased risk of cardiovascular complications.
methodsRetrospective observational study in 62 kidney transplant patients (60% deceased donor, 26% pre-dialysis transplant) aged between 4 and 18 years, with a median post-transplant time of 5 years. Blood pressure (BP) was measured during consultations; ambulatory blood pressure monitoring (ABPM) was performed, along with blood and urine analysis, echocardiography, and kidney ultrasound.
resultsOf the 62 patients evaluated, 27 (44%) were receiving antihypertensive treatment. ABPM detected hypertension in 25 patients (40%), of whom 11 (41%) were already on treatment. Fifteen patients (24%) presented with masked hypertension. Younger patients showed a significantly higher prevalence of abnormal ABPM findings (p = 0.011). Truly normotensive patients received lower doses of corticosteroids and exhibited a lower prevalence of overweight and left ventricular hypertrophy (LVH) compared with the other groups (controlled, uncontrolled, and untreated). Seventy-three percent of patients exhibited a loss of physiological nocturnal dipping. LVH (24%) was influenced by ambulatory systolic blood pressure and the presence of prior rejection (p = 0.016). Loss of systolic dipping significantly contributed to the presence of LVH in the multivariate analysis (OR, 0.829; p = 0.033).
conclusionsOur cohort shows poor BP control (masked HTN detected in 1 out of every 4 patients). Effective control of systolic BP appears to be crucial in preventing LVH. Our findings support the routine use of ABPM in pediatric transplant recipients, even in those under antihypertensive treatment.
