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

aimLipoprotein (a) [Lp(a)] is a well-established risk factor for cardiovascular disease independent of low-density lipoprotein-cholesterol (LDL-C). The Lp(a) concentrations were inconsistent between the immunoassays. This study aimed to investigate whether harmonization of Lp(a) measurements can be achieved using a serum panel value assigned with the IFCC-endorsed mass spectrometry-based reference measurement procedure (IFCC-MS-RMP).

methodsWe measured the Lp(a) concentrations using five Lp(a) immunoassays in 40 panel sera provided by the Centers for Disease Control and Prevention (CDC), and 500 Japanese subjects enrolled in the Bunkyo Health Study. Of the five immunoassays, only the Roche Lp(a) assay was traceable to the WHO-IFCC reference material SRM2B. Lp(a) concentrations in CDC samples were also determined by IFCC-MS-RMP, provisionally calibrated to SRM2B. Lp(a) concentrations were expressed in mass units (mg/dL) for most reagents, but in SI units (nmol/L) for Roche's reagent and IFCC-MS-RMP.

resultsIn the CDC panel sera, all immunoassays, including Roche's reagent, showed good correlations with IFCC-MS-RMP. In the Bunkyo Health Study samples, all immunoassays showed good correlations with Roche's reagent (r

conclusionWe achieved harmonization of Lp(a) measurements with five immunoassays using a serum panel value assigned with the IFCC-MS-RMP.
