Forest Plot of Standardized Intervention Effects at 6-, 12-, and 18-Month Follow-up in 309 Patients With Breast Cancer 
Standardized outcome scores were applied using fitted models by subtracting the sample mean score from each score and dividing by the SD. Models were adjusted for randomization strata of age (<60 years or ≥60 years) and treatment modality (none, adjuvant chemotherapy, or neoadjuvant chemotherapy). HRQOL indicates health-related quality of life.
