Primary outcomes were the number of SLNs identified, rate of failed mapping, identification of metastatic SLNs, and adverse reactions to dye tracer between ICG-RI and BD-RI techniques. Secondary outcomes were costs associated with the two techniques. Demographic information included tumour type, previous axillary surgery or neoadjuvant therapy, and body mass index (BMI). Intraoperative information included the number of nodes identified with each technique and operation duration. Postoperative information included hospital admission duration, complications (adverse reactions and anaphylaxis to tracers), significant complications related to SLN biopsy (Clavien-Dindo grade ≥III), number of metastatic lymph nodes on histopathology, and follow-up visit information up to 90 days postoperative. Anaphylaxis was defined as a severe multisystemic reaction based on the National Institute of Health.
