In the 14-days glucocorticoid group, MBL deficiency and MBL concentrations independently predicted a lower re-exacerbation risk [multivariate cox regression, MBL < 500 ng/mL, HR 0.35 (95% CI 0.16, 0.79), p = 0.01; MBL (concentrations), HR 1.05 per 200 ng/mL increase (95% CI 1.02, 1.08), p ≤ 0.01]. Here, MBL2 is linked to hyperinsulinemic hypoglycemia, familial, 4.
