Application analysis of transfected cell method for detecting AChR antibodies in MG patients.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study aimed to establish a technical process for detecting nicotinic acetylcholine receptor (nAChR) antibodies using the transfected cell method and evaluate its application in the serological diagnosis of myasthenia gravis (MG), thereby enhancing diagnostic efficiency. Cell transfection technology was used to introduce various nAChR subunit combinations into HEK293 cells for antibody detection. Indirect immunofluorescence (IIF) was utilized to test nAChR antibodies in serum samples from 85 MG patients, and the results were compared for consistency with those of enzyme-linked immunosorbent assay (ELISA).The combination of fetal and adult AChR subunits in transfected cells exhibited the highest sensitivity for detecting serum antibodies in patients with MG. The prepared cell slides demonstrated excellent consistency with the ELISA kit results for 85 MG patients, yielding a Kappa value of 0.769, indicating excellent agreement between the two methods. Co-transfection of multiple AChR subunits successfully generated a cell expressing clustered nAChRs, establishing a highly sensitive detection technique for nAChR antibodies. This technique is invaluable for serological detection of patients with MG, facilitating early disease detection, condition assessment, and therapeutic guidance.
