CEL and diabetes mellitus: In contrast, protein-bound CML and CEL were inversely and significantly associated with sC5b-9 in diabetes (protein-bound CML, β = −0.24 [−0.42, −0.06], protein-bound CEL, β = −0.21 [−0.38, −0.05]), but not in individuals without diabetes (protein-bound CML, β = 0.05 [−0.07, 0.16], protein-bound CEL, β = −0.02 [−0.12, 0.08]).
