Frailty and sex differences in blood pressure control in older adults.
Article in Scientific reports, 2026. 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
We aimed to examine the prevalence of frailty in older adults with hypertension and its association with suboptimal blood pressure (BP), with a particular focus on differences by sex. The study was conducted at two major hospitals in Vietnam from 2023 to 2024. Frailty was defined by a Clinical Frailty Scale of ≥ 4. Suboptimal BP was defined as systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg. There were 1038 participants (326 female, mean age 73 years). The prevalence of frailty was 28.6%, higher in female (35.3%) than male participants (25.6%). The overall rate of suboptimal BP was 26.7%. In female participants, the frail had a significantly higher rate of suboptimal BP (33.9%) compared to the non-frail (20.9%), but no significant differences among male. In the logistic model adjusted for age, education, marital status, physical exercise, falls, coronary heart disease, diabetes, chronic kidney disease, osteoarthritis, heart failure, stroke, atrial fibrillation, osteoporosis, chronic obstructive pulmonary disease, duration of hypertension, monotherapy/combination therapy, and medication adherence score, the odds ratios of frailty on suboptimal BP were 2.01 (95% CI 1.08-3.76) in female participants, 0.92 (95% CI 0.59-1.44) in male, female-to-male ratio of odds ratios 2.18 (95% CI 1.01-4.70). These findings highlight the need for sex-specific approaches in managing hypertension in older populations.
