Fig. 3From: Surgical drainage after limb salvage surgery and endoprosthetic reconstruction: is 30 mL/day critical?Total drain output and resection length. Linear regression was performed to analyze the potential relationship between total drain output and resection length. A scatterplot with best-fit line is shown for total drain output (L, liters) and resection length (Pearson’s correlation coefficient R = 0.19, p = 0.001)Back to article page
