Fig. 2From: Surgical drainage after limb salvage surgery and endoprosthetic reconstruction: is 30 mL/day critical?Drain output and duration of drains. Linear regression was performed to analyze the potential relationship between total drain output and duration of drains. A scatterplot with best-fit line is shown for total drain output (L, liters) and duration of surgical drains (Pearson’s correlation coefficient R = 0.79, p < 0.001)Back to article page
