Table 2.
Subgroup analysis of operative time between IMN and MIPO (based on AO/OTA, age and wound type)
| Variable | No. of Trials | No. of Participants | Mean Difference | P value |
|---|---|---|---|---|
| AO/OTA | ||||
| 43A | 2 | 127 | −12.78 [−19.75, −5.81] | 0.0003 |
| 42 | 4 | 271 | −6.75 [−22.37, 8.87] | 0.4 |
| Age(years) | ||||
| >40 | 4 | 596 | −9.25 [−24.62, 6.12] | 0.24 |
| <40 | 3 | 123 | −7.58 [−14.89, −0.26] | 0.04 |
| Wound type | ||||
| Closed and open fracture | 2 | 138 | −19.16 [−33.44, −4.88] | 0.09 |
| Only closed fracture | 5 | 581 | −3.50 [−13.42, 6.41] | 0.49 |
P value <0.05 means there is a statistical difference in the results.
