Angiotensin II Type 1 Receptor Blocker Usage Prevents Oxidative Stress and Muscle Dysfunction in HIV.
Article in Fundamental & clinical pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe aimed to elucidate the role of Angiotensin II type 1 receptor (AT1R) blocker usage in muscle wasting and dysfunction related to HIV. RESEARCH DESIGN AND
methodsAppendicular skeletal muscle mass, higher and lower limb strength, and physical fitness were determined in people living with HIV (PWH) using AT1R blockers users (n = 33), angiotensin-converting enzyme (ACE) inhibitors (n = 28), or not using antihypertensive drugs (n = 33). Groups had similar age, sex, race, BMI, and time of HIV infection. Muscle biopsies were performed to determine the abundance of AT1R, the relative abundance of selected proteins related to proteolysis, antioxidant enzymes, and oxidative stress. Plasma angiotensin II, IL-6, and TNF-alpha were also determined.
resultsPWH using AT1R blocker presented higher strength, physical fitness, and muscle mass than PWH using ACE inhibitors or not using antihypertensive drugs. Although both PWH using AT1R blockers and ACE inhibitors presented reduced angiotensin II plasma levels, only PWH using AT1R blockers presented lower skeletal muscle AT1R activation, lower plasma oxidative stress markers, lower skeletal muscle oxidative stress (4-HNE), and proteolysis markers (Atrogin-1, Murf-1).
conclusionAT1R blocker usage protects against oxidative stress and activated proteolysis, contributing to the prevention of muscle wasting and dysfunction among PWH.
