| Question | Why it matters | Example |
|---|---|---|
| What is the outcome definition? | Ensures consistent classification | "Clinic attendance within 30 days" must define eligible visit types |
| When is the outcome assessed? | Aligns data collection with protocol timing | Day 7, day 28, six months, discharge |
| What is the source document? | Supports verification and audit | Clinic register, laboratory report, follow-up form |
| What format is required? | Supports analysis | Binary, date, numeric value, category, time-to-event |
| Are derived variables needed? | Guides raw variable capture | Days from discharge to attendance |
| How will missing outcomes be handled? | Prevents ambiguity in analysis | Lost to follow-up, refused, died, unable to contact |
