Significant Associations in Adolescents with Diabetes. (A) An association between HbA1c and mean implicit time in the type 1 group suggesting that as HbA1c increased there was a significant increase in implicit time (y = 0.13x + 26.21, R2 = 0.17, P < 0.01). To make the relationship between HbA1c and implicit time visible, the range of the Y-axis is limited to 25-30 ms. (B) Retinal Thickness and Amplitude (C) An association between type 2 diabetes duration and mfERG amplitude suggesting that as duration increases mfERG increases (y = 24.85x + 168.05, R2 = 0.41, P = 0.01).
