Group	Pre-op QOL	1 week post-op	1 month post-op	1 year post-op	Improvement	Statistic	P value
Low-risk	58.7 ± 11.1	64.3 ± 10.4	70.1 ± 8.9	75.0 ± 7.6	16.3 ± 4.8	F = 7.86	0.031
Moderate-risk	53.5 ± 9.2	62.4 ± 8.3	67.2 ± 7.4	73.8 ± 6.9	20.3 ± 5.1	F = 10.13	0.012
High-risk	49.8 ± 13.0	63.5 ± 10.5	71.1 ± 8.9	78.2 ± 8.0	28.4 ± 6.31	F = 15.49	< 0.001

¹Indicates statistically significant difference compared to other groups (P < 0.01).

Higher scores indicate better quality of life. P values were adjusted using Bonferroni correction where applicable. Missing data were handled using the linear mixed model. “Improvement” refers to change from baseline (Δ value).
