Table 1 Summary of the proportions of individuals who would receive a primaquine (PQ) dose within the defined therapeutic dosing range of 0.15–0.38 mg base/kg body weight, an underdose (<0.15 mg base/kg), and a supratherapeutic dose (>0.38 mg base/kg)

From: An optimised age-based dosing regimen for single low-dose primaquine for blocking malaria transmission in Cambodia
