Fourteen‐year longitudinal observation of a female patient with ADH who first presented at age 26 months with rickets and iron deficiency. (A) Phosphorus metabolism; (B) the corresponding iron metabolism. Before starting oral iron, she received only conventional rickets therapy, which was fully stopped at age 9.25 years. Continuous oral iron therapy is depicted as a dark box, and 3‐month intermittent oral iron supplementation as a dashed box. The vertical lines represent start and end of iron supplementation period. Analysis of all her biochemical data points revealed that serum phosphate correlated best with ferritin (r = 0.65, p = .003) and calcitriol concentrations (r = 0.62, p = .008).
