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

Background The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines lowered the threshold of blood pressure (BP) for hypertension to 130/80 mm Hg. However, the clinical significance of isolated diastolic hypertension (IDH) according to the cutoff value of the 2017 ACC/AHA guidelines was uncertain. Methods and Results We analyzed the claims database of Japan Medical Data Center (a nationwide epidemiological database). We excluded individuals who were aged <20 years, had systolic hypertension, were taking antihypertensive medication, or had prevalent cardiovascular disease, and studied 1 746 493 individuals (mean age, 42.9±10.7 years; 961 097 men [55.0%]). The average observational period was 1107±855 days. Stage 1 IDH, defined as diastolic BP 80 to 89 mm Hg, and stage 2 IDH, defined as diastolic BP ≥90 mm Hg, were found in 230 513 (13.2%) and 16 159 (0.9%) individuals, respectively. Compared with individuals with normal diastolic BP, individuals with stage 1 and stage 2 IDH were older and more likely to be men. Prevalence of classic risk factors was higher in patients with IDH. Kaplan-Meier curves showed that stage 1 and stage 2 IDH were associated with a higher incidence of cardiovascular events, defined as myocardial infarction, angina pectoris, and stroke. Multivariable analysis showed that stage 1 (hazard ratio [HR], 1.17) and stage 2 (HR, 1.28) IDH were independently associated with a higher incidence of cardiovascular events. Subgroup analyses showed that the association of IDH with cardiovascular events was seen irrespective of age and sex. Conclusions The analysis of a nationwide epidemiological database showed that IDH based on the cutoff value in the 2017 ACC/AHA BP guidelines was associated with an elevated risk of subsequent cardiovascular events.
