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.

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.

2 · 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

objectiveStatins have been shown to be beneficial for the prevention of cardiovascular events. In elderly individuals, the efficacy of statins remains controversial and the comparative effect of statins has not been assessed.

methodsMEDLINE, Embase, and the Cochrane Central database were searched for randomized controlled trials that assessed statins in older patients.

resultsSeventeen trials were analyzed. When used for secondary prevention, statins were associated with reduced risk of cardiovascular events, all-cause mortality, cardiovascular mortality, revascularization, and stroke. When used for primary prevention, statins reduced the risk of myocardial infarction and revascularization, but did not significantly affect other outcomes. A modest difference between pharmaceutical statin products was found, and high-quality evidence indicated that intensive atorvastatin had the greatest benefits for secondary prevention.

conclusionsIn secondary prevention, evidence strongly suggests that statins are associated with a reduction in the risk of all-cause mortality, cardiovascular events, cardiovascular mortality, and revascularization. However, differences in the effects of various statins do not appear to have significant effects on therapy in secondary prevention for the elderly.
