In The Lancet Global Health, Sophie Sarrassat and colleagues¹ report on the first cluster randomised controlled trial of a radio intervention to reduce child mortality. The study is exceptional in its design and ambition: a systematic review of 111 mass media interventions to improve child survival found that only 32 used moderate to strong evaluation designs and only one measured an actual health outcome.² This elegant Burkinabé trial bucks all trends.

掀起波澜：无线电能降低儿童死亡率吗？

在《柳叶刀全球卫生》中，Sophie Sarrassat及其同事¹报告了第一项针对降低儿童死亡率的放射干预的整群随机对照试验。这项研究在设计和野心方面都是出类拔萃的：对111项提高儿童生存率的大众媒体干预措施的系统评价发现，只有32项采用了中度到强力的评估设计，而只有一种评估了实际的健康结果。²这项优雅的Burkinabé试验与所有趋势背道而驰。
