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.

2 · The registry

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

introductionNocturnal hypertension is clinically important for patients with type 2 diabetes (T2D), considering its strong correlation with cardiovascular events. We aim to test the hypothesis that the sodium-glucose cotransporter 2 inhibitor, luseogliflozin, ameliorates nocturnal hypertension more effectively than a dipeptidyl peptidase (DPP)-4 inhibitor in patients with T2D. METHODS AND ANALYSIS: This study is a multicentre, prospective, randomised, open-label, blinded endpoint parallel-group trial. Sixty participants with T2D and hypertension who have been treated with a DPP-4 inhibitor for more than 4 weeks and who have a glycated haemoglobin A1c (HbA1c) level of 6.0%-9.0% will be randomised based on age, body mass index (BMI) and HbA1c to continue taking their DPP-4 inhibitor or to switch to luseogliflozin 2.5 mg once daily for 8 weeks. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) will be performed twice at baseline and at the end of the study. All participants will continue their diet and exercise therapy, and the doses of concomitant medications will not be adjusted during the study. The primary endpoint is the effect of luseogliflozin on the mean change in systolic blood pressure (SBP) during the night, as measured by ABPM. The secondary endpoints are mean change in diastolic blood pressure (DBP) during the night, 24 hours of SBP and DBP, daytime SBP and DBP, pulse rate, BP M-value, trough SBP and DBP for 1 hour before the next dose, and other laboratory parameters. The sample size was calculated for a two-sided test at 90% power for the detection of a difference between treatments. ETHICS AND DISSEMINATION: The Ethics Review Board of Hokkaido University Hospital has approved the protocol. The results will be disseminated in peer-reviewed journals and at scientific conferences. TRIAL REGISTRATION NUMBERS: The University Hospital Medical Information Network (UMIN000031451); Japan Registry of Clinical Trials (jRCTs011180019); Pre-results.
