Four of our Reviews have challenged dogmas, and created policy debates

  • Routine deworming of school children: Cochrane Review questioned the evidence behind the efforts in Africa and Asia by the World Bank and NGOS to regularly deworm children. This has created controversy, although organizations in the USA continue to promote this. However, a recent replication by the London School of Hygiene and Tropical Medicine of their study raises questions about its reliability.
  • Low carbohydrate diets for weight loss: in South Africa, low carbohydrate, high saturated fat diets are widely promoted. The Consortium carried out a systematic review that questioned the claims being made by the advocates, and resulted in considerable debate in the national press and television.
  • Quality of private providers: a systematic review questioned the dogma that quality in the private (for profit and not for profit) sector is higher in low- and middle-income countries (LMIC), with research indicating it is poor in both.
