1.1. Objective: This project aims to investigate the diagnostic value of anti-Ro-52, anti-CENP-B, and AMA in Sjogren's syndrome
and systemic sclerosis.
1.2. Methods: We constructed the Meta-analysis to evaluate the existing experimental data and obtain the advantages of the three antinuclear antibodies compared with traditional test items using specific data processing methods and evaluated their value in the diagnosis as well as the differential diagnosis of Sjogren's syndrome and systemic sclerosis. During the process of paper collection, we strictly followed the principle of PICOS to screen the literature, trying to include the literature with a large sample size, controversial and influential results which would make the results of this Meta-analysis more valuable. In this study, Revman and Stata software was used for data processing, and the forest map was drawn to analyze the difference in antibody-positive rate, age, and gender distribution, and other factors. At the same time, a funnel plot was used to evaluate the bias of literature results.
