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

backgroundCeliac disease (CD) and type 1 diabetes mellitus (DM1) are genetically associated pathologies, and it is frequent that a patient presents both. The simultaneous detection of autoimmune markers of CD and DM1 would be a rational strategy to improve their diagnosis. The aim of this work was the expression and purification of recombinant human tissue transglutaminase and the development of an immunoassay based on flow cytometry (FloCMIA multiplex) for the simultaneous and discriminative detection of autoantibodies to tissue transglutaminase (tTgA) and two of the main markers of DM1-glutamic acid decarboxylase autoantibodies (GADA) and protein tyrosine phosphatase-related IA-2 autoantibodies (IA-2A).

resultsRecombinant tTg was purified from E. coli bacteria, yielding ≈ 9.7 mg of 90-95% pure protein/L of bacterial culture. For the immunoassay, a "double paratope" model was performed and 40 serum samples of control individuals and 25 recently diagnosed patients with CD and/or DM1 were assayed. The analytical sensitivity of FloCMIA multiplex was 67% for tTgA, 76% for GADA and 71.4% for IA-2A. The specificity was 89%, 93% and 90% for tTgA, GADA and IA-2A, respectively.

conclusionsThe FloCMIA multiplex immunoassay was successfully developed as a flow cytometry-based platform for the simultaneous and discriminative screening of CD and DM1 autoantibodies. This method offers a practical, accessible, and high-throughput solution, significantly reducing costs (up to tenfold) and operational time compared to traditional assays. By utilizing a commonly available flow cytometer, detecting all immunoglobulin isotypes, and eliminating radioactive materials, FloCMIA provides a safer, more inclusive, and sensitive tool, enabling earlier therapeutic intervention and improving large-scale population screening.
