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.

致编辑在其实用的整群随机临床试验中，Shet等[ ^1]报告了在印度，基于社区的父母教育和咨询以及常规治疗对儿童贫血治愈率的显着影响。在全球范围内，贫血已上升到流行的比例，2010年估计患病率为32.9％，导致6836万岁的残疾人生活。²因此，预防贫血和减轻其不良影响的策略具有重要的公众意义。为了填补这一知识空白，Shet等人¹提出了一种有效的策略，可以指导决策者和从业人员在人群水平上加强对贫血的控制。但是，我们担心结果外推和数据管理。
