To the Editor In their pragmatic cluster randomized clinical trial, Shet et al1 reported a perceivable effect of community-based parental education and counseling annexed with usual treatment on children’s anemia cure rate in India. Globally, anemia has escalated to epidemic proportions, with an estimated prevalence of 32.9% in 2010, causing 68.36 million years lived with disability.2 Hence, strategies to prevent anemia and mitigate its adverse effects are of major public importance. To fill this gap in knowledge, Shet et al1 have proposed an effective strategy that might guide policy makers and practitioners to enhance anemia control at a population level. However, we are concerned about result extrapolation and data management.
