Note: The numbers of matched sets were as follows: for urine: total observations = 325 after the model has excluded missing values, 111 cases remain, 106 of which have two matched controls and 5 of which have 1 matched control; for serum, total observations = 255 after the model has excluded missing values, 92 cases remain, 89 of which have two controls and 3 of which have 1 control.
