Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data will be collected from the databases of Sun Yat-sen Memorial Hospital and other centers, including baseline population characteristics, medical records, Hcy levels and measurement timing, MTHFR genotypes, ovarian function indicators, metabolic markers, rheumatic, immune, and coagulation parameters, chromosome and ultrasound results, assisted reproductive data, and pregnancy outcomes. The data will be stored in Excel spreadsheets and retrieved for analysis using R software.
