A possible explanation may lie in the power of analysis facilitated by a larger sample size of participants that reported of not receiving any IPTp-SP at Maamobi due to G6PD status compared to Kpone on-Sea where virtually every participant received SP, or other possible factors such as maternal nutrition, malaria history or other infections that may be specific to the site but which we are unaware of. The gene discussed is G6PD; the disease is infection.
