Abbreviations: CGM = continuous glucose monitoring; DM = diabetes mellitus; Ha = alternative hypothesis; HbA1c = hemoglobin A1c; Pr = probability; SMBG = self-monitoring of blood glucose.

These comparisons were found to be statistically significant.

Ha: mean ! = 188.4412; Ha: mean>188.4412; Pr(T < t) = 0.0208; Pr(|T| > |t|) = 0.0415
