Primary Outcome Measures:
  • Proportion of Participants With at Least One Symptomatic Hypoglycemic Event [ Time Frame: 30 days: first day of Ramadan (August 11) to last day of Ramadan (September 10) ]
    Symptomatic hypoglycemic event was determined based on the participant's self-reported symptoms including faintness, headache, confusion, anxiety, sweating, tremor, palpitation, nausea, pallor, dizziness, hunger, and sudden behavioral change.


Secondary Outcome Measures:
  • Proportion of Participants With at Least One Symptomatic or Asymptomatic Hypoglycemic Event [ Time Frame: 30 days: first day of Ramadan (August 11) to last day of Ramadan (September 10) ]
    Hypoglycemic event was based on the participant's self-report and/or finger-stick blood glucose level. Symptomatic hypoglycemic symptoms included faintness, headache, confusion, anxiety, sweating, tremor, palpitation, nausea, pallor, dizziness, hunger, and sudden behavioral change.
