After evaluating all the physiological responses, the number of leaves, leaf thickness, leaf area, leaf dry weight, and root dry weight were measured. Leaf thickness was measured at the utmost center of the leaf using Vernier calipers, and the dry weight was measured after drying the leaf at 80 °C for 48 h in a dryer (DS-80-5, Dasol Scientific Co. Ltd., Gyeonggido, Korea). Thereafter, tree/root ratio (T/R ratio), specific leaf area (SLA), leaf area ratio (LAR), and leaf weight ratio (LWR) were calculated. One-way analysis of variance (ANOVA) was performed for the CO₂ exchange rate and chlorophyll fluorescence response by leaf temperature, and the significance among each treatment was determined at 5% (Duncan’s multiple range test). The relation among chlorophyll content, carotenoid content, and growth response effects due to climate change and photoenvironment was assessed using two-way ANOVA. SPSS Statistics Program (Version 19.0) was used for all statistical analyses.

All statistical analysis was performed with the SPSS statistics program version 19.0 (SPSS, Inc., Chicago, IL, USA). The Chi-square test was used to compare the baseline tumor characteristics, such as age, menopausal status, family history of breast cancer, histological cancer type, clinical stage, axillary lymph nodal status, surgical technique used, random assignment to a chemotherapy-containing regimen, the site of initial recurrence and the initial time to recurrence. PFS and MSR curves were calculated using the Kaplan-Meier method, and the differences between the luminal group and the non-luminal group were compared using the log-rank test. A p-value < 0.05 was considered statistically significant.
