Article in Cardiovascular diabetology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03718585 (Whole Exome Sequencing Analysis Project in Chronic Kidney Disease Patients With Nocturnal Hypertension), which is not on this map. Cited by 17 papers.

1 · What the graph read from it

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.

Abstract

backgroundHypertensive patients with reduced blood pressure fall (BPF) at night are at higher risk of cardiovascular events (CVE).

methodsWe evaluated in hypertensive diabetic patients, if a reduced nocturnal BPF can precedes the development of diabetic nephropathy (DN). We followed 70 patients with normal urinary albumin excretion (UAE) for two years. We performed 24-hours ambulatory BP monitoring in baseline and at the end of the study.

resultsFourteen (20%) patients (GI) developed DN (N = 11) and/or CVE (n = 4). Compared to the remaining 56 patients (GII) in baseline, GI had similar diurnal systolic (SBP) and diastolic BP (DBP), but higher nocturnal SBP (138 +/- 15 vs 129 +/- 16 mmHg; p < 0.05) and DBP (83 +/- 12 vs 75 +/- 11 mmHg; p < 0,05). Basal nocturnal SBP correlated with occurrence of DN and CVE (R = 0.26; P < 0.05) and with UAE at the end of the study (r = 0.3; p < 0.05). Basal BPF (%) correlated with final UAE (r = -0.31; p < 0.05). In patients who developed DN, reductions occurred in nocturnal systolic BPF (12 +/- 5 vs 3 +/- 6%, p < 0,01) and diastolic BPF (15 +/- 8 vs 4 +/- 10%, p < 0,01) while no changes were observed in diurnal SBP (153 +/- 17 vs 156 +/- 16 mmHg, NS) and DBP (91 +/- 9 vs 90 +/- 7 mmHg, NS). Patients with final UAE < 20 microg/min, had no changes in nocturnal and diurnal BP.

conclusionsOur results suggests that elevations in nocturnal BP precedes DN and increases the risk to develop CVE in hypertensive patients with T2DM.
