Efficacy and Safety of Allisartan Isoproxil/Amlodipine in Patients with Essential Hypertension: A Phase III, Multicenter, Double-Blind, Parallel-Group, Randomised study.
Trial report in Journal of human 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
This multicenter, double-blind, parallel-group, randomised controlled phase III study evaluated the efficacy and safety of the Allisartan Isoproxil 240 mg /Amlodipine 5 mg (ALI/AML) combination compared with ALI 240 mg monotherapy in patients with mild-to-moderate essential hypertension. Patients aged 18 to 70 years with mean sitting systolic blood pressure (msSBP) between 140 and <180 mmHg and mean sitting diastolic blood pressure (msDBP) between 90 and <110 mmHg were randomised 1:1 to receive ALI/AML or ALI once-daily for 12 weeks after a 4-week treatment with ALI, followed by an open-label extension period with ALI/AML up to week 52. A total of 199 patients were randomised (ALI/AML: n = 99, ALI: n = 100) with 169 completing the study. Baseline characteristics were comparable between groups. After 12 weeks of randomisation, the reduction in msSBP (primary endpoint) was significantly greater in the ALI/AML group vs the ALI group (-18.3 vs. -9.3 mmHg, p < 0.001). Reductions in msDBP (-6.0 vs. -1.9 mmHg, p < 0.001) and 24-hour mean ambulatory systolic/diastolic blood pressure (-19.9/-10.1 vs. -6.9/-4.2 mmHg) were more pronounced in the ALI/AML group. Additionally, a greater proportion of patients achieved the BP response and target office BP in the ALI/AML group compared to the ALI group (53.6% vs. 25.5%, p < 0.001; 40.2% vs. 20.4%, p=0.0026). AML/ALI combination was generally safe and well tolerated, with sustained efficacy up to 52 weeks. The study concluded that ALI/AML offers a convenient, single-pill option for effective BP reduction in hypertensive patients.
