N=26 for the correlations of HbA1c, glycated albumin, fructosamine and 1,5-AG with each other. N=21 for correlations involving CGM glucose indices.

Negative correlation. For simplicity of viewing, the negative signs have been omitted. All correlations with 1,5AG are negative because lower is more abnormal for 1,5-AG and higher is more abnormal for the other measures.
