Comparison of preoperative weight and height measurements across different age groups. (A) Bar graph illustrating mean preoperative weight (kg) across five age categories (14–25, 26–35, 36–45, 46–55, and 56 + years). (B) Bar graph showing mean preoperative height (cm) across the same age categories. Error bars represent standard deviation. Horizontal bars with p-values indicate statistical significance between age groups.
