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

objectiveTo compare the implications of four widely used cholesterol screening and treatment guidelines by applying them to a population in the United Kingdom.

designGuidelines were applied to population based data from a cross sectional study of cardiovascular disease and risk factors.

settingNewcastle upon Tyne, United Kingdom. SUBJECTS: General population sample (predominantly of European origin) of 322 men and 319 women aged 25-64 years.

main outcome measuresProportions recommended for screening and treatment.

methodsCriteria from the British Hyperlipidaemia Association, the British Drugs and Therapeutics Bulletin (which used the Sheffield table), the European Atherosclerosis Society, and the American national cholesterol education programme were applied to the population.

resultsProportions recommended for treatment varied appreciably. Based on the British Drugs and Therapeutics Bulletin guidelines, treatment was recommended for 5.3% (95% confidence interval 2.9% to 7.7%) of men and 3.3% (1.5% to 5.3%) of women, while equivalent respective values were 4.6 (2.3 to 6.9) and 2.8 (1.0 to 4.6) for the British Hyperlipidaemia Association, 23% (18.4% to 27.6%) and 10.6% (7.3% to 14.0%) for the European Atherosclerosis Society, and 37.2% (31.9% to 42.5%) and 22.2% (17.6% to 26.8%) for the national cholesterol education programme. Only the British Hyperlipidaemia Association and Drugs and Therapeutics Bulletin guidelines recommend selective screening. Applying British Hyperlipidaemia Association guidelines, from 7.1% (4.3% to 9.9%) of men in level one to 56.7% (51.3% to 62.1%) of men in level three, and from 4.4% (2.1% to 6.7%) of women in level one to 54.4% (48.9% to 59.9%) of women in level three would have been recommended for cholesterol screening. Had the Drugs and Therapeutics Bulletin guidelines been applied, 22.2% (16.5% to 27.9%) of men and 12.2% (8. 6% to 15.8%) of women would have been screened.

conclusionsWithout evidence based guidelines, there are problems of variation. A consistent approach needs to be developed and agreed across the United Kingdom.
