All data were analyzed with IBM SPSS Statistics Version 28.0 (IBM Corp., Armonk, New York, United States). Descriptive statistics are presented as number of cases and percentages for dichotomous and ordinal variables, whereas continuous parametric variables are presented as mean and standard deviation (SD). Non-parametric variables are presented as median with interquartile range (IQR). Fisher’s exact test was used to compare categorical variables containing small number of cases (n ≤ 5).
Spearman’s rank-order correlation tests were conducted to determine the association between amount and location of identified SLNs by blinded handheld gamma-camera assessment and lymphoscintigraphy for each patient.
On the basis of the false-negative rate for SLNB in this cohort, the sensitivity (true positives/(true positives + false negatives)) and negative predictive value (NPV; (true negatives/(true negatives + false negatives)) were calculated.
Overall, a p-value ≤ 0.05 was considered to be statistically significant.
