The rapid detection of human HLA-B*27 gene based on BASIC isothermal detection.
Article in Scientific reports, 2025. 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
Ankylosing spondylitis (AS) is a chronic, inflammatory arthritis of the spine and peripheral joints which is known to have a strong association with the human leukocyte antigen B27 (HLA-B27). Quantitative real-time PCR and flow cytometry are the predominant methods for HLA-B27 gene and antigen, respectively, which are too time-consuming and labor-intensive to realize rapid analysis. Therefore, a rapid diagnostic tool is highly required. In this study, we developed a rapid HLA-B*27 detection platform (namely BASIC) by combining our previously invented BASIS isothermal amplification method with the widely used CRISPR/Cas12a signal output tool. The BASIS can efficiently amplify all HLA-B*27 genotypes by using a set of universal primers, which target the conserved regions. The amplicons are subsequently applied to CRISPR/Cas12a analysis. The CRISPR/Cas12a recognizes the pathogenic HLA-B*27 amplicons specifically by using a well-designed gRNA, thereby achieving fluorescence signal output. Our results showed that the BASIC can be completed in 1 h with analytical sensitivity up to 100 aM. It could resist interference of homologous genes, hemoglobin, bilirubin, and triglyceride. For clinical sample detection, the BASIC offered completely consistent results with qPCR. Given the advantages of sensitivity, specificity, simplicity and rapidity, the BASIC was demonstrated a promising HLA-B*27 gene rapid detection tool for the early screening and diagnosis of AS.
