a decreasing trendp =0.400
In patients aged ≥60 years, the 1st_CGM was associated with a significant decrease in blood glucose levels over time (from 219 mg/dL to 156 mg/dL, p <0.05), in contrast with the 2nd_CGM that only showed a decreasing trend in blood glucose levels (from 171 mg/dL to 155 mg/dL, p =0.400), which was not significant.
