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

objectiveEvidence favors apolipoprotein B (apoB) over LDL cholesterol as a predictor of cardiovascular events, but data are lacking on coronary artery calcification (CAC), especially in type 2 diabetes, where LDL cholesterol may underestimate atherosclerotic burden. We investigated the hypothesis that apoB is a superior marker of CAC relative to LDL cholesterol. RESEARCH DESIGN AND

methodsWe performed cross-sectional analyses of white subjects in two community-based studies: the Penn Diabetes Heart Study (N = 611 type 2 diabetic subjects, 71.4% men) and the Study of Inherited Risk of Coronary Atherosclerosis (N = 803 nondiabetic subjects, 52.8% men) using multivariate analysis of apoB and LDL cholesterol stratified by diabetes status.

resultsIn type 2 diabetes, apoB was associated with CAC after adjusting for age, sex, and medications [Tobit regression ratio of increased CAC for 1-SD increase in apoB; 1.36 (95% CI 1.06-1.75), P = 0.016] whereas LDL cholesterol was not [1.09 (0.85-1.41)]. In nondiabetic subjects, both were associated with CAC [apoB 1.65 (1.38-1.96), P < 0.001; LDL cholesterol 1.56 (1.30-1.86), P < 0.001]. In combined analysis of diabetic and nondiabetic subjects, apoB provided value in predicting CAC scores beyond LDL cholesterol, total cholesterol, the total cholesterol/HDL cholesterol and triglyceride/HDL cholesterol ratios, and marginally beyond non-HDL cholesterol.

conclusionsPlasma apoB, but not LDL cholesterol, levels were associated with CAC scores in type 2 diabetic whites. ApoB levels may be particularly useful in assessing atherosclerotic burden and cardiovascular risk in type 2 diabetes.
