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.

Abstract

The marked sentences are the ones the graph read a number from.

purposeResults from a Phase III, European, non-inferiority trial in elderly (age ≥65 years) patients with primary hyperlipidemia or mixed (combined) dyslipidemia demonstrated significantly greater reductions in LDL-C for pitavastatin versus pravastatin across 3 pair-wise dose comparisons (1 mg vs 10 mg, 2 mg vs 20 mg, and 4 mg vs 40 mg, respectively). The present study investigated whether pitavastatin 4 mg is superior to pravastatin 40 mg in LDL-C reduction in adults (18-80 years old) with primary hyperlipidemia or mixed (combined) dyslipidemia.

methodsThis was a Phase IV, multicenter, randomized, double-blind, double-dummy, active-control superiority study conducted in the United States. Patients with baseline LDL-C levels of 130 to 220 mg/dL (inclusive) and triglyceride levels ≤400 mg/dL after a 6-week washout/dietary stabilization period were randomized to 12 weeks of once-daily treatment with either pitavastatin 4 mg or pravastatin 40 mg.

findingsA total of 328 subjects (164 per treatment arm) were randomized (mean age, 57.9 years [76% were aged <65 years]; 49.4% women; mean body mass index, 30.2 kg/m(2)) to treatment. The median percent change in LDL-C from baseline to the week 12 endpoint was -38.1% for pitavastatin 4 mg and -26.4% for pravastatin 40 mg; the difference in median percent change between treatments was -12.5% (P < 0.001). Differences between treatments in median percent reductions from baseline for apolipoprotein B, total cholesterol, and non-HDL-C were also significant in favor of pitavastatin (P < 0.001). Both treatments significantly (P < 0.001) increased HDL-C and decreased triglycerides, but the differences between treatments were not statistically significant. The overall rate of treatment-emergent adverse events was 47.6% (78 of 164) for pitavastatin and 44.5% (73 of 164) for pravastatin. Myalgia was reported by 3 patients (1.8%) in the pitavastatin group and by 4 patients (2.4%) in the pravastatin group. There were no reports of myositis or rhabdomyolysis. IMPLICATIONS: Pitavastatin 4 mg demonstrated superior LDL-C reductions compared with pravastatin 40 mg after 12 weeks of therapy in adults with primary hyperlipidemia or mixed (combined) dyslipidemia. There were no new safety findings in the trial. Clinical Trials.gov identifier: NCT01256476.
