Trial report in Preventive medicine, 2016. The graph read 2 numbers from its abstract, feeding 2 cells of the map, but none could be read as for or against, so it casts no vote. It also reports 2 associations that do not count as treatment evidence, such as OR 3.98 (3.30 to 4.81) for lipids. It is linked to trial NCT01610609 (Center for Advancing Equity in Clinical Preventive Services Project 2), which is not on this 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.

Abstract

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

backgroundAlthough cholesterol guidelines emphasize cardiovascular disease (CVD) risk to guide primary prevention, predictors of statin use in practice are unknown. We aimed to identify factors associated with a cholesterol treatment discussion and statin prescribing in a high-risk population.

methodsWe used data from a trial conducted among participants in community health centers without CVD or diabetes and a 10-year coronary heart disease (CHD) risk≥10%. Cholesterol treatment discussion was assessed at 6months and statin prescription at 1year. We used logistic regressions to identify factors associated with each outcome.

resultsWe analyzed 646 participants (89% male, mean age 60±9.5years). Cholesterol treatment discussion occurred in 19% and statin prescription in 12% of participants. Ten-year CHD risk was not associated with treatment discussion (OR 1.11 per 1 SD increase, 95% CI 0.91-1.33) but was associated with statin prescription (OR 1.41 per 1 SD increase, 95% CI 1.13-1.75) in unadjusted models. After adjusting for traditional CVD risk factors that contribute to CHD risk, low-density lipoprotein cholesterol (LDL-C) was independently associated with statin prescription (OR 1.82 per 1 SD increase, 95% CI 1.66-1.99). Antihypertensive medication use was independently associated with both cholesterol treatment discussion (OR 3.68, 95% CI 2.35-5.75) and statin prescription (OR 3.98, 95% CI 3.30-4.81). Other drivers of CVD risk (age, smoking, and systolic blood pressure) were not associated with statin use.

conclusionsSingle risk factor management strongly influences cholesterol treatment discussions and statin prescribing patterns. Interventions that promote risk-based statin utilization are needed.
