  "nct": "NCT04867785",
  "window": "calendar",
  "basis": "Baseline Through Study Completion (Up to 280 Days)",
  "reason": "The time frame is a period on the trial's calendar; the description's \"regardless of adherence to study drug or initiation of rescue medication\" defines who is counted, which under rule 4 does not change the code, and nothing says events were followed after stopping the drug, so rule 3 gives calendar."
 },
 {
  "nct": "NCT04881760",
  "window": "calendar",
  "basis": "Baseline Through End of Safety Follow-up (Up to 52 Weeks)",
  "reason": "The period is set by the trial's calendar and safety follow-up, not tied to the last dose; \"regardless of adherence to study drug\" qualifies the analysis population (rule 4) rather than saying participants were followed off drug, so rule 3 gives calendar."
 },
 {
  "nct": "NCT05051579",
  "window": "calendar",
  "basis": "Baseline through Week 38 (36 weeks with 2 weeks safety follow up)",
  "reason": "A calendar period plus fixed follow-up, like the codebook's \"baseline to week 56 plus 7 weeks of follow-up\" example; the description only defines the population counted (rule 4), so rule 3 gives calendar."
 },
 {
  "nct": "NCT05260021",
  "window": "calendar",
  "basis": "Baseline Up to Week 56",
  "reason": "The description says participants \"were included in safety analyses, regardless of adherence\", which states who is counted (rule 4), and its safety sets name study periods, not follow-up after stopping the drug; with nothing either way, rule 3 gives calendar."
 },
 {
  "nct": "NCT05691712",
  "window": "calendar",
  "basis": "Baseline up to week 44",
  "reason": "The time frame is a calendar period; \"regardless of adherence\" describes the analysis population (rule 4), and \"collected per the treatment regimen, irrespective of each dose level\" says how events were grouped by arm, not that the period ends with treatment, so rule 3 gives calendar."
 },
 {
  "nct": "NCT05963022",
  "window": "calendar",
  "basis": "Baseline up to week 44",
  "reason": "The time frame is a calendar period; \"regardless of adherence\" describes the analysis population (rule 4), and \"collected per the treatment regimen, irrespective of each dose level\" concerns grouping by arm, not a period tied to or freed from taking the drug, so rule 3 gives calendar."
