Evaluation of a Rapid Immunochromatographic Assay and Two Enzyme-Linked Immunosorbent Assays for Detection of IgM-Class Antibodies to Zika Virus.

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
There are currently five serologic assays available for detection of anti-Zika virus (ZIKV) IgM-class antibodies with U.S. Food and Drug Administration emergency use authorization. Among these are the Chembio DPP Zika IgM system (DPP Zika ICA; Chembio, Medford, NY), a rapid immunochromatographic assay (ICA), and the InBios ZIKV Detect 2.0 IgM antibody capture enzyme-linked immunosorbent assay (ZIKV 2.0 MAC-ELISA; InBios international, Inc., Seattle, WA), which has replaced the original InBios ZIKV Detect MAC-ELISA. We evaluated performance of these three serologic assays using 72 specimens characterized by plaque reduction neutralization testing (PRNT) for the presence or absence of neutralizing antibodies (NAbs) to ZIKV, dengue virus (DENV), and West Nile virus (WNV). The InBios ZIKV 2.0 MAC-ELISA was "presumptive Zika positive" in all 15 PRNT-confirmed ZIKV samples, while the Chembio DPP Zika ICA was nonreactive in three (20%) and the InBios ZIKV MAC-ELISA was negative in four (27%). The Chembio DPP Zika ICA and InBios ZIKV 2.0 MAC-ELISA showed >95% specificity in 22 ZIKV/DENV-seronegative specimens and in 13 samples positive for NAbs to non-ZIKV flaviviruses. Comparatively, the InBios ZIKV MAC-ELISA was "presumptive" or "possible Zika positive" in 8 of 12 WNV or DENV PRNT-positive samples and in 12 of 22 PRNT-seronegative sera. Our findings suggest that replacement of the InBios ZIKV MAC-ELISA with the InBios ZIKV 2.0 MAC-ELISA will lead to fewer samples requiring PRNT, minimizing unnecessary anxiety among patients ultimately determined to be seronegative for ZIKV and DENV by PRNT and alleviating some of the testing burden on laboratories performing PRNT.
