Fig. 1
Calcium levels over time by group. This figure illustrates changes in calcium levels at three time points: preoperation (pre-op), postoperation day 1 (post-op day 1), and postoperation week 1 (post-op week 1). The blue line represents the control group (Group 0), and the orange line represents the experimental group (Group 1). Shaded areas indicate the confidence intervals for the calcium level changes in both groups. Both groups exhibited a decrease in calcium levels on post-op day 1, followed by a subsequent increase by post-op week 1. The experimental group (orange line) shows a more stable calcium level postoperatively compared to the control group.
