1 · What the graph read from 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.

This paper's own estimate is on a different scale from the rest of the cell, so it is not drawn here.

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.

objectiveCoronary artery disease (CAD) is presently the major cause of mortality and morbidity. Anti-hyperlipidemic treatment is one of the main treatment steps in the management of CAD. Statins are the cornerstones in this treatment. Ezetimibe can be reliably used, when statins prove ineffective in treatment, or to reduce their side effects. In the present study we examined the effects of high-dose pravastatin (40 mg) and low-dose pravastatin (10 mg) + ezetimibe (10 mg) combination therapy on lipid and glucose mechanism, as well as inflammation.

methodsThis study registered 100 cases. Of the cases, 50 [57.1 +/- 11.1 years (24 (48%) females and 26 (52%) males)] were administered 40 mg/day pravastatin (group 1) and 50 [53.2 +/- 12.2 years (27 (54%) females and 23 (46%) males)] were administered 10 mg pravastatin + 10 mg ezetimibe (group 2).

resultsIn group 1, total cholesterol fell from 231.1 +/- 83.5 mg/dl to 211.3 +/- 37.2 mg/dl (p = 0.03), triglyceride from 243.5 +/- 96.8 mg/dl to 190.9 +/- 55.2 mg/dl (p = 0.003), and LDL cholesterol from 165.7 +/- 29.7 mg/dl to 133.4 +/- 26.6 mg/dl (p = 0.02). In group 2, total cholesterol dropped from 250.9 +/- 51.8 mg/dl to 187.9 +/- 34.9 mg/dl (p = 0.001), triglyceride from 270.3 +/- 158.9 mg/dl to 154.6 +/- 60.7 mg/dl (p = 0.001), and LDL cholesterol from 158.1 +/- 47.5 mg/dl to 116.9 +/- 26.4 mg/dl (p = 0.001). Insulin resistance decreased from 4.05 +/- 2.31 to 3.16 +/- 1.90 (p = 0.07) in group 1 and from 2.96 +/- 1.50 to 2.05 +/- 0.55 (p = 0.009) in group 2. High sensitive C-reactive protein fell from 6.69 +/- 6.11 mg/l to 3.02 +/- 1.70 mg/l (p = 0.01) in group 1 and from 6.36 +/- 2.06 mg/l to 2.68 +/- 1.69 mg/l (p = 0.001) in group 2.

conclusionBoth therapy regimes are effective. However, we found that low-dose pravastatin and ezetimibe combination therapy is more effective than high-dose pravastatin therapy on lipid metabolism, glucose metabolism and inflammation.
