Table 3. Comparisons of Outcomes Between Laparoscopic and Open Colorectal Resection Within FT Programs.
| Outcome | Studies | Number | Effect estimate (95% CI) | Heterogeneity | Test for overall effect |
|---|---|---|---|---|---|
| Mortality | 5 | 598 | RR = 2.26 (0.62 - 8.22) | x2 = 0, I2 = 0%, P = 0.50 | P = 0.21 |
| Overall complications | 7 | 714 | RR = 1.31 (1.12 - 1.54) | x2 = 6.00, I2 = 0%, P = 0.42 | P = 0.0007 |
| Readmission rates | 6 | 678 | RR = 1.33 (0.79 - 2.22) | x2 = 6.24, I2 = 20%, P = 0.28 | P = 0.28 |
The P values of comparisons are given in the column labeled “Test for overall effect”.
