Insignificant interference of Elevit in pregnant women serum samples with HBsAg immunoassay on Sysmex.
Article in Journal of clinical laboratory analysis, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundThe pregnant women often take Elevit as the multivitamin supplement which has a substantial amount of biotin that might potentially interfere with the HBsAg immunoassay performed by the prevalent Sysmex system in clinical laboratories. We therefore wanted to determine this, so that the therapeutic intervention on the hepatitis B virus infection during pregnancy and birth would not be missed.
methodsElevit was both serially diluted in vitro and orally taken by healthy volunteers whose blood samples were then taken at different time points. All samples were added to a serum sample with a known result of HBsAg and then measured by Sysmex. The Abbott immunoassay system was used as the control as it involves no streptavidin-biotin binding in the reagent set. Besides, the HBsAg results were compared between the pregnant women taking or not taking Elevit.
resultsBiotin at 25 ng/mL in the Elevit started to suppress the HBsAg and reached about 50% suppression at 100 ng/mL on Sysmex. In the volunteers, biotin reached the peak concentration at 2 hours. However, their blood samples showed no suppression on the HBsAg detection by Sysmex. In samples from pregnant women who took Elevit, the HBsAg results by Sysmex were highly correlated with those by Abbott (R
conclusionElevit intake in pregnant women shows no significant interference with HBsAg immunoassay on Sysmex.
