Effects of Captopril and Losartan on Cardiac Stereology in Rats with Renovascular Hypertension.
Article in Iranian journal of medical sciences, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Captopril, an angiotensin-converting enzyme inhibitor, and losartan, an angiotensin II receptor blocker, are used for the treatment of hypertension, but their effects on cardiac stereology are unknown. This study, therefore, aimed to examine their effects on cardiac stereology in rats with renovascular hypertension. Methods: This study was conducted at Histomorphometry and Stereology Research Centre, and Cardiovascular Pharmacology Research Lab, Department of Pharmacology, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran, in August 2015 to August 2016. Fourty-eight rats were allocated to six groups (n=8 per each group): a sham group, which received a vehicle (distilled water) and five renal artery-clipped groups, which received the vehicle, captopril (50 or 100 mg/ kg/day), or losartan (25 or 50 mg/kg/day). After four weeks, the animals' systolic blood pressures (mm Hg) were measured, and the total volumes of their heart, myocardium, endocardium, matrix, and myocardial vessels (mm Results: The renal artery-clipped rats receiving the vehicle had a significantly higher systolic blood pressure (P<0.001); heart weight (g) (P<0.001); and total volume of the heart (P<0.001), myocardium (P=0.020), endocardium (P=0.009), and myocardial vessels (P=0.008); as well as a significantly lower number of cardiomyocytes (P=0.010) and Purkinje cells (P=0.005), than did the rats in the sham group. The renal artery-clipped rats receiving captopril or losartan had a significantly lower systolic blood pressure (P<0.001), heart weight (P=0.007), and total volume of the heart (P<0.001), myocardium (P<0.001), endocardium (P=0.027), and myocardial vessels (P=0.004) than did the renal artery-clipped rats receiving the vehicle. Neither captopril nor losartan prevented a reduction in the number of Purkinje cells, but captopril at the higher dose attenuated cardiomyocyte loss (P=0.010). Conclusion: Captopril and losartan lowered the systolic blood pressure and cardiac hypertrophy but failed to prevent Purkinje cell loss. Captopril only at the higher dose prevented cardiomyocyte loss. Captopril exerted a greater inhibitory effect on cardiac stereology, which warrants further research.
