a
Adjusted for age, sex and ethnicity.
b
Due to very small CIs, these ORs have been calculated by dividing the laboratory result by its standard deviation.
c
Due to positive skew, these results underwent a natural logarithm transformation. Logn results are in normal text with original results in italics (analyses performed using logn results).
