  3. bGrading not available for one study (ID 2) with 288 AEs and a further 30 AEs from another 2 studies, all RCTs (primaquine: day 28, 145; day 7, 85; day 3, 39; no-primquine: day 28, 48; day 7, 27; day 3, 11)
  4. cEight studies had haemoglobinuria data in controlled studies, 1516 participants in the primaquine arm and 680 in the no primaquine arm. These data include 19 records of haemoglobinuria that were not reported as AEs. One study with 813 participants had haemoglobinuria data in uncontrolled studies. There was no haemoglobinuria reported after day 3
  5. dExact day of SAE within 7 days of follow-up not known for one haematological SAE in uncontrolled studies
