Association Between Antihypertensive Treatment Discontinuation and the Development of Intracerebral Hemorrhage in Japanese Patients With Hypertension: The LIFE Study.

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
backgroundHypertension is the principal risk factor for intracerebral hemorrhage (ICH), and blood pressure control is reliant on consistent adherence to antihypertensive treatment. This study examined the association between antihypertensive treatment discontinuation and ICH occurrence in Japanese patients with hypertension.
methodsThis nested case-control study was conducted using claims data from the LIFE (Longevity Improvement & Fair Evidence) study from residents of 4 Japanese municipalities enrolled in public medical insurance or public assistance programs. The participants comprised people with hypertension between April and October 2017 and were followed up from November 2017 to March 2022 to identify ICH occurrence. Cases with ICH were matched with controls without ICH in a 1:10 ratio based on sex and age. Participants without any claims data for hypertension care for ≥4 months were regarded as discontinuing antihypertensive treatment. Conditional logistic regression was performed to examine the association between treatment discontinuation and ICH occurrence. Covariates included atrial fibrillation and flutter, diabetes, Charlson Comorbidity Index score, antithrombotic, and statin use.
resultsOf 62 674 patients with hypertension, 5699 (9.1%) developed ICH during follow-up. Participants who discontinued antihypertensive treatment had significantly higher odds for developing ICH (odds ratio, 3.77 [95% confidence interval, 3.43-4.14];
conclusionsAntihypertensive treatment discontinuation significantly increased the risk of developing ICH in Japanese patients with hypertension. Regular medical visits and treatment adherence may help to prevent ICH development in these patients, thus reducing their clinical and economic burden.
