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.

backgroundIndividuals at high risk of cardiovascular disease (CVD) are undertreated.

aimTo evaluate the effectiveness of a programme of targeted, nurse-led case finding for CVD prevention in primary care. DESIGN AND

settingTargeted case finding for CVD prevention was implemented in urban West Midlands general practices between February 2009 and August 2012, and evaluated as a stepped wedge cluster randomised trial.

methodUntreated patients aged 35-74 years and at ≥20% 10-year CVD risk were identified, invited for assessment by a project nurse, and referred to their GP for treatment initiation. The primary outcome was the proportion of high-risk patients prescribed antihypertensives or statins after exposure to the intervention compared with an equivalent period of time prior to exposure. Secondary outcomes included assessment of CVD risk factors.

resultsIn 26 sequentially randomised general practices the exposed group consisted of 2926 untreated high-risk patients identified at the start of the intervention, with 2969 patients identified at the start of the unexposed period. The trial was well balanced in terms of age, sex, and cardiovascular risk factors. In the exposed period 19.7% of patients were prescribed antihypertensives or statins, and 10.8% of patients in the unexposed period. After adjustment for clustering and temporal effects the risk difference was 15.5% (95% CI = 3.9 to 27.1, P = 0.009). Assessment of lipid levels increased significantly, at 26.4% (99% CI = 5.3 to 47.5, P = 0.001)

conclusionTargeted case finding programmes can increase the number of high-risk patients started on antihypertensive and statin treatment.
