The impact of blood pressure variability and African Caribbean ethnicity on the progression of diabetic kidney disease in type 1 diabetes.

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
aims/hypothesisBlood pressure variability (BPV) is a risk factor for kidney disease progression in hypertension and type 2 diabetes; however, the role of BPV in kidney disease in type 1 diabetes is unknown. The aim of this study was therefore to determine whether BPV has an impact on kidney disease progression in an ethnically diverse cohort of people with type 1 diabetes.
methodsWe studied 3079 people (median age 36 [range 18-85] years; 50% female; 78.5% White, 10.9% African Caribbean, 4.5% Asian, 6.1% Other) with type 1 diabetes and baseline eGFR >45 ml/min per 1.73m
resultsOver a 14 year period, 272 people (8.8%) reached the primary endpoint. All BPV metrics for SBP and DBP were significantly associated with the primary endpoint. ARVs of SBP and DBP and African Caribbean ethnicity emerged as risk factors in multivariable analyses, independent of traditional risk factors, including baseline blood pressure, eGFR, HbA CONCLUSIONS/
interpretationIn people with type 1 diabetes, SBP and DBP variability are associated with kidney disease progression. Further studies are needed to investigate if BPV is a modifiable risk factor for kidney disease progression.
