Efficacy and Safety of Olmesartan in the Treatment of Mild-to-Moderate Essential Hypertension in Chinese Patients.
Article in Clinical drug investigation, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
BACKGROUND AND
objectiveHypertension is very prevalent in the Chinese population in Taiwan. Chinese people frequently experience bothersome cough when receiving angiotensin-converting enzyme (ACE) inhibitors, and angiotensin II (AT(1)) receptor antagonists are thus relatively more frequently used in this context. In this trial we studied the effectiveness of a new AT(1) receptor antagonist, olmesartan, in the treatment of Chinese patients with mild-to-moderate essential hypertension. PATIENTS AND
methodsThe present study was a double-blind, randomised, multicentre trial to compare the efficacy and safety profiles of two AT(1) receptor antagonists, olmesartan and losartan, in the treatment of Chinese patients with mild-to-moderate essential hypertension. 126 adults were randomised to receive either once-daily olmesartan 20mg or once-daily losartan 50mg for 12 weeks. There were 49 evaluable patients in the olmesartan group and 57 in the losartan group.
resultsAt baseline, neither diastolic (DBP) nor systolic (SBP) blood pressures were significantly different between the two study groups. Trough blood pressures were measured and recorded for the evaluation of treatment effect. After drug treatment for 4, 8 and 12 weeks, SBP and DBP values were significantly decreased in both groups of patients. However, both SBP and DBP were significantly lower in the olmesartan group than in the losartan group after treatment. At the end of treatment, DBP values were 87.0 +/- 8.6mm Hg versus 91.6 +/- 8.7mm Hg (p < 0.001) and SBP values were 129.5 +/- 12.6mm Hg versus 135.4 +/- 12.1mm Hg (p < 0.001) in the olmesartan and losartan groups, respectively. After 4 weeks of treatment, the reduction in BP values was larger in the olmesartan group than in the losartan group (decreases in DBP of 12.1 +/- 8.4mm Hg vs 7.2 +/- 6.8mm Hg [p < 0.005] and in SBP of 15.1 +/- 13.0mm Hg vs 10.3 +/- 10.1mm Hg [p < 0.05] for the olmesartan and losartan groups, respectively). Patients treated with either drug experienced only mild adverse reactions, such as dizziness, cough, headache and neck pain, all of which occurred at low frequencies. There were no significant changes in laboratory parameters.
conclusionBoth olmesartan and losartan are effective and safe in the treatment of Chinese patients with mild-to-moderate essential hypertension. Olmesartan 20mg once daily is more potent and has a more rapid antihypertensive effect than losartan 50mg once daily in the treatment of mild-to-moderate hypertension in Chinese patients.
