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

backgroundSclerostin alters bone formation. The precise and reproducible measurement of sclerostin concentrations in biological samples is important for assessment of metabolic bone disease. We determined sclerostin concentrations in serum and plasma using two commercially available ELISA.

methodsWe measured sclerostin concentrations in serum or heparin-plasma obtained from 25 normal human subjects using two commercial ELISA available from Biomedica Medizinprodukte GmbH and TECOmedical AG.

resultsWith the Biomedica assay, serum sclerostin concentrations were 0.99 ± 0.12 ng/ml (mean ± sem), and plasma concentrations were 1.47 ± 0.13 ng/ml (paired t test, P < 0.001). With the TECO assay, serum sclerostin levels were 0.71 ± 0.05 ng/ml, and plasma sclerostin concentrations were 0.80 ± 0.06 ng/ml (paired t test, P < 0.001). Serum and plasma sclerostin concentrations were significantly different when determined by the two assays (serum, P = 0.015; plasma, P < 0.001). Recovery of added recombinant sclerostin to serum was less than expected with both Biomedica and TECO assays (P < 0.001, paired t test).

conclusionsThe concentrations of sclerostin in serum and plasma are different when determined by the two assays. Serum or plasma sclerostin concentrations with current assays should be interpreted with caution. The data suggest that the same assay should be used for comparing groups of patients or patients being followed longitudinally. Standardization of sclerostin assays is required before being introduced into general clinical laboratory use.
