Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Arm I:Sentinel Node Resection+Conventional Axillary Dissection | Sentinel node resection immediately followed by axillary dissection~conventional surgery: Sentinel node resection immediately followed by axillary dissection. | 314 | 1,136 | OG000 |
| Group 2 | Arm II: Sentinel Node Resection Followed by Node Examination | Sentinel node resection followed by node examination then axillary dissection if positive sentinel node.~Sentinel node resection followed by node examination: Sentinel node resection followed by node examination then axillary dissection if positive sentinel node. No axillary dissection for negative sentinel node. | 192 | 1,151 | OG001 |
