a nonsignificant trendp = 0.07
Based on linear regression analysis adjusted for preoperative lesion size, the robotic approach was associated with a nonsignificant trend toward lower blood loss (β = −199.4 mL, 95% CI −418.4 to 19.6, p = 0.07) and shorter hospitalization (β = −2.1 days, 95% CI −2.7 to −1.6, p < 0.001) ( Table 2 ).
