Steps in the example process of randomization and blinding
| What to do | Who does it | Comments | |
|---|---|---|---|
| 1 | Generate a random allocation sequence | Colleague | Figure 6B |
| 2 | Shuffle all animal ID#s | Colleague | |
| 3 | Assign shuffled ID#s to allocation table | Colleague | Table 1 |
| 4 | Generate group ID#s | Colleague | For analysis, e.g., Rx = 1, Ctrl = 2 |
| 5 | Prepare syringes of substances to be administered | Experimenter | Don't label individual syringes! Group in separate beakers (X/Ctrl) |
| 6 | Label each syringe with an animal ID# | Colleague | Refer to allocation table |
| 7 | Collect data, referenced to animal ID# | Experimenter | |
| 8 | Provide analyst with group ID#s | Colleague | Statistical comparison of groups |
| 9 | Reveal group identity after analysis is complete | Colleague |
