Clinical Practice of Two Measurements of Home Blood Pressure on Each Occasion in Patients with Chronic Kidney Disease.
Article in Cardiorenal medicine, 2015. 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
BACKGROUND/
aimsAlthough several guidelines propose two or three measurements of home blood pressure (HBP) on each occasion, the actual status of multiple measurements is not clear in the practical management of hypertension. We surveyed the details regarding two measurements of HBP in patients with chronic kidney disease (CKD).
methodsHBP was measured twice every morning and evening over 7 consecutive days in 175 CKD patients. The distribution of the differences between two BP values (2nd - 1st BP) and their association with BP parameters were evaluated.
resultsThe 2nd - 1st morning systolic BP (SBP) and diastolic BP (DBP) differences were -2.3 ± 4.1 and -0.4 ± 2.6 mm Hg, respectively. The proportion of 2nd - 1st morning SBP differences >0 mm Hg was 31.7% in a total of 1,195 measurements. Eighty patients (45.7%) had days with a difference ≤-5 mm Hg and days with a difference ≥5 mm Hg in morning SBP during 7 days. The multivariate regression analysis of the SD values of 2nd - 1st morning SBP as a dependent variable showed that the SD value of the 1st morning SBP (β = 0.65, p < 0.001) was a significant determinant.
conclusionAlthough the 2nd SBP was 2-3 mm Hg lower than the 1st SBP in the population as a whole, various differences were found for each subject during 7 days. 2nd - 1st BP variability might be associated with day-by-day 1st BP variability.
