Length of stay for FlexVATS cohort compared to thoracotomy and VATS. Data are presented as median ± interquartile range. Statistical significance was assessed using the Kruskal–Wallis test followed by Dunn’s test for pairwise multiple comparisons of the ranked data. Statistical significance was set at P < 0.05. **Significant difference (p = 0.002); ns not significant.
