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.

In a subset of 26 previously untreated patients, combined pravastatin (mean daily dose 22 mg) and gemfibrozil (mean daily dose 1,154 mg) therapy lowered total cholesterol by 25% (p < 0.001), triglycerides by 53% (p = 0.0001), LDL cholesterol by 14% (p = 0.24), and increased high-density lipoprotein (HDL) cholesterol by 20% (p = 0.012).

4 · The registry

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

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

backgroundCombined HMG-CoA reductase inhibitor and fibric acid derivative therapy is often necessary for the effective reduction of concentrations of low-density lipoprotein (LDL) cholesterol and triglycerides in patients with mixed hyperlipidemia; however, the potential risk of myopathy has limited the use of these agents. HYPOTHESIS: This study evaluated long-term safety and efficacy of combined pravastatin and gemfibrozil therapy.

methodsEighty-three patients with hyperlipidemia were treated with combined pravastatin and gemfibrozil therapy for a median of 44 months (range 9-78 months). Plasma lipids, serum liver function tests, creatinine, and creatinine kinase (CK) levels were measured every 3 to 4 months.

resultsOne patient developed myalgia with a normal CK level after 4 months of combination therapy. Three patients had transient elevations in CK levels that ranged from 3 to 5 times the upper limits of "normal" and that returned to normal upon repeat testing. Liver function tests did not change significantly from baseline. In a subset of 26 previously untreated patients, combined pravastatin (mean daily dose 22 mg) and gemfibrozil (mean daily dose 1,154 mg) therapy lowered total cholesterol by 25% (p < 0.001), triglycerides by 53% (p = 0.0001), LDL cholesterol by 14% (p = 0.24), and increased high-density lipoprotein (HDL) cholesterol by 20% (p = 0.012).

conclusionPravastatin and gemfibrozil therapy is safe and efficacious in patients with mixed hyperlipidemia. The long-term safety results are consistent with other reports on follow-up of shorter duration.
