Comparison of the effects of pitavastatin versus pravastatin on coronary artery plaque phenotype assessed by tissue characterization using serial virtual histology intravascular ultrasound.
Trial report in Heart and vessels, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Thin-cap fibroatheroma (TCFA) is the most common type of vulnerable plaque and is the precursor of plaque rupture. However, rupture of a TCFA is not the only mechanism underlying thrombus formation or acute coronary syndrome. Although statin therapy changes the composition of coronary artery plaques, the effects of statins, particularly different types of statins, on plaque phenotype have not been fully examined. This study compared the effects of pitavastatin versus pravastatin on coronary artery plaque phenotype assessed by virtual histology (VH) intravascular ultrasound (IVUS) in patients with angina pectoris (AP). Coronary atherosclerosis in nonculprit lesions was evaluated using VH-IVUS at baseline and 8 months after statin therapy; analyzable IVUS data were obtained from 83 patients with stable AP (39 patients treated with pitavastatin and 44 with pravastatin) and 36 patients with unstable AP (19 patients treated with pitavastatin and 17 with pravastatin). Pitavastatin had a strong effect on reducing pathologic intimal thickening (PIT), especially in patients with unstable AP, but had no impact on VH-TCFA or fibroatheroma (FA). By contrast, pravastatin had weak effects on reducing PIT, VH-TCFA, or FA. Increases in the number of calcified plaques were observed for both statins. In conclusion, pitavastatin and pravastatin changed coronary artery plaque phenotype as assessed by VH-IVUS in patients with AP. However, the effects of these statins on coronary artery plaque phenotype were different.
