Disparities in Initial Antihypertensive Intensity by Sex, Race and Ethnicity in Newly Treated Patients With Hypertension.
Article in American journal of hypertension, 2025. 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
backgroundSex, race, and ethnicity disparities in hypertension (HTN) treatment intensity have been previously described. It remains unclear if these disparities occur at treatment onset and whether they can be explained by differences in clinical factors.
methodsWe conducted a retrospective cross-sectional study of adults with newly treated HTN using linked EHR + claims data from OneFlorida + Consortium. We included Florida Medicaid & Medicare-recipients diagnosed with HTN and prescribed ≥ 1 first-line antihypertensive during 2013-2020. We used generalized linear models to estimate differences in total therapeutic intensity score (TTIS)-a patient's total daily dose (TDD) divided by recommended maximum TDD for a drug, summed across entire regimen-by sex, race, and ethnicity. We then modeled the same, controlling for demographics, blood pressure, and relevant comorbidities.
resultsIn total 4,094 patients (mean age 58 ± 16; female 57.6%; White 56.7%) were included. We observed variations in the initiation of antihypertensive classes by sex, race and ethnicity. In univariate analyses, men averaged 7.6% (95% CI: 3.9%-11.3%) greater TTIS versus women and Black individuals averaged 10.5% (95% CI: 6.6%-14.3%) greater TTIS versus White individuals, whereas no disparities were observed by ethnicity. After adjusting for clinical factors, these disparities persisted: men had 7.6% (95% CI: 3.9%-11.4%) greater TTIS versus women, and Black individuals had 17.9% (95% CI: 13.8%-21.9%) greater TTIS versus White individuals.
conclusionsWe observed disparities in treatment intensity by sex and race that were not explained by differences in clinical factors. There was sex-based variation in practice patterns, and Black individuals received more intensive initial antihypertensive therapy than White individuals.
