SPADI (total scores, pain, and disability subscales) and pain (rest, night, and on activity) scores—landmark versus CT guided injection
| Outcome measure (max score) | Week 1 | Week 4 | Week 12 | |||
|---|---|---|---|---|---|---|
| Mean change | Difference in mean change between groups (95% CI) | Mean change | Difference in mean change between groups (95% CI) | Mean change | Difference in mean change between groups (95%CI) | |
| There are no significant differences between the two approaches at any time interval. | ||||||
