Chios Mastic in Well-Controlled Hypertension: Findings From the HYPER-MASTIC Randomized Controlled Trial.
Trial report in Pharmacology research & perspectives, 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
Residual cardiovascular risk persists in patients with adequately controlled hypertension, driven partly by inflammation, oxidative stress and endothelial dysfunction. Chios mastic (Pistacia lentiscus var. Chia) has shown antihypertensive, antioxidant and vascular effects in experimental and clinical settings. This trial evaluated whether Chios mastic supplementation confers additional cardiovascular benefits in well-controlled hypertensive individuals. In this double-blind, randomized, placebo-controlled trial, 106 adults with stable, well-controlled hypertension and variable cardiovascular risk, based on SCORE2, received low-dose Chios mastic (1500 mg/day), high-dose Chios mastic (2800 mg/day) or placebo for 3 months. Primary endpoints were changes in 24-h ambulatory systolic and diastolic blood pressure. Secondary endpoints included vascular function, oxidative stress and proteasome activity in peripheral blood mononuclear cells and red blood cells. Transcriptomic profiling was performed in a predefined high-risk subgroup. Chios mastic supplementation was well tolerated, with high adherence confirmed by dose-dependent increases in plasma masticadienonic and isomasticadienonic acids. No significant between-group differences were observed in 24-h systolic or diastolic blood pressure after the intervention. Oxidative stress markers and proteasome activity remained unchanged across groups. In high-risk participants, mastic supplementation induced distinct transcriptomic changes, particularly in pathways related to endothelial junction organization and vascular integrity. Overall, in adults with well-controlled hypertension and low baseline cardiovascular risk, Chios mastic supplementation did not lower blood pressure over 3 months, likely reflecting a ceiling effect. Transcriptomic findings suggest biologically meaningful vascular effects in individuals with higher residual cardiovascular risk, supporting future investigation in higher-risk populations.
