WebThe area under the receiver operating characteristic curve was 0.791 (95% CI, 0.731–0.840). Preoperative HCLR at a high level (>1.3) was positively correlated with large tumor size, TNM stage, microvascular invasion, and recurrence. The mean OS and PFS in patients with HCLR >1.3 were significantly shorter than in those with HCLR ≤1.3. Webarea shows displacement/distance, depending on whether it is a speed or a velocity time graph. Work done is directly proportional to distance, hence as rectangles have a larger area, given that the time (length) and magnitude of speed/velocity (height) is the same, more work is done in the rectangular graph.
