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.

Abstract

The Cholesterol Lowering Atherosclerosis Study (CLAS) was a randomized, placebo-controlled, angiographic trial testing combined colestipol-niacin therapy in 162 subjects. Two-year results (CLAS-I) showed decreased atherosclerosis progression and increased regression. We now describe a subgroup of 103 subjects treated for 4 years (CLAS-II). Changes in blood lipid, lipoprotein-cholesterol, and apolipoprotein levels were maintained, and at 4 years significantly more drug-treated subjects demonstrated nonprogression (52% drug- vs 15% placebo-treated) and regression (18% drug- vs 6% placebo-treated) in native coronary artery lesions. Significantly fewer drug-treated subjects developed new lesions in native coronary arteries (14% drug- vs 40% placebo-treated) and bypass grafts (16% drug- vs 38% placebo-treated). These results confirm CLAS-I findings and indicate that regression can continue for 4 years. They reaffirm the need for early initiation of vigorous long-term lipid lowering therapy in coronary bypass subjects.
