Authors' judgement |
Support for judgement |
| Adequate sequence generation? |
Low risk |
Adequate: "women were randomly allocated". Similar to the authors previous study (Frydman 1992)".
Comment: Probably done. |
| Allocation concealment? |
Low risk |
Adequate: "Used a balanced randomisation list obtained by premutation block". |
| Blinding?
All outcomes |
Low risk |
Adequate: "Double blind procedure". Placebo and mifepristone tablets were visually identical and externally produced. |
| Incomplete outcome data addressed?
All outcomes |
Low risk |
No exclusions. All participants were reported for all outcomes. |
| Free of selective reporting? |
Low risk |
Adequate as data complete. |
