1Each patient had pica at first diagnosis of and at recurrence of iron deficiency or depletion. Data are presented as mean ± 1 SD. Abbreviations: MCV, mean corpuscular volume; RBC, red blood cells; RDW, red blood cell distribution width; SI, serum iron; TIBC, total iron-binding capacity; TS, transferrin saturation; SF, serum ferritin.
2Comparisons of mean values at first diagnosis and at recurrence of iron deficiency or depletion were made using Student's two-tailed t-test.
