Efficacy, Tolerability, and Acceptability of Iron Hydroxide Polymaltose Complex versus Ferrous Sulfate: A Randomized Trial in Pediatric Patients with Iron Deficiency Anemia

Figure 1

Acceptability score in pediatric patients with iron deficiency anemia receiving oral iron therapy in the form of iron hydroxide polymaltose complex (IPC) or ferrous sulfate. Acceptability was assessed using the Wong-Baker scale [15], on which a “happy face” (score 0) stands for no difficulties, while a “sad face” (score 5) indicates that the child refused or was forced to take the medicine.
