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

backgroundWe investigated in a longitudinal, multicenter, cohort study whether combined lipid apheresis and lipid-lowering medication can reduce extremely high levels of lipoprotein(a) (Lp[a]) and thus prevent major adverse coronary events (MACE) more efficaciously than lipid-lowering medication alone.

methodsEligible patients had coronary artery disease and Lp(a) levels > or =2.14 micromol/l (95th percentile). All patients received lipid-lowering medications alone until maximally tolerated doses were no longer effective, followed by combined lipid apheresis and lipid-lowering medication. The rates of the primary outcome, MACE, were recorded for both periods.

resultsA total of 120 patients were included. The mean duration of lipid-lowering therapy alone was 5.6+/-5.8 years, and that of apheresis was 5.0+/-3.6 years. Median Lp(a) concentration was reduced from 4.00 micromol/l to 1.07 micromol/l with apheresis treatment (P<0.0001); the corresponding mean annual MACE rate per patient was 1.056 versus 0.144 (P<0.0001).

conclusionsLowering of Lp(a) levels by apheresis was efficacious and safe, and we recommend this therapy for patients in whom maximally tolerated doses of medication alone have failed to control coronary artery disease-associated events.
