Even after adjusting for factors such as age, primiparity, BMI, hypertension, systolic blood pressure and diastolic blood pressure, aspartate aminotransferase, alanine aminotransferase, fasting blood glucose, and total cholesterol, the correlation between a history of cardiac arrhythmia and GDM remained statistically significant (adjusted OR, 1.78; 95% CI, 1.61 to 1.97; p< 0.001; Figure 1). The gene discussed is GPT; the disease is cardiac arrhythmia.
