End interval for interval 1 is visit 2 (study midpoint) and for interval 2 is visit 3 (study end). Comparative correlations were calculated (27), and Steiger Z (1 bar) values were AUC-180 overall/A1C vs. AUC-180 overall/1,5-AG (Z = −3.01,

P < 0.01), AUC-180 interval 1/A1C vs. AUC-180 interval 1/1,5-AG (Z = −1.99, † P < 0.05), AUC-180 interval 2/A1C vs. AUC-180 interval 2/1,5-AG (Z = −2.61, *P < 0.01), MPMG/A1C vs. MPMG/1,5-AG (Z = −2.24, †P < 0.05).
