Mean EQ-5D index and severity of depression: displays the relationship between the mean EQ-5D-5L index score, a measure of HRQOL, and the severity of depression among the study population. The x-axis represents the severity of depression, measured using a validated questionnaire, and is divided into four categories: no depression, mild depression, moderate depression, and severe depression. The y-axis shows the mean EQ-5D-5L index score for each category of depression severity. The legend provides information about the mean EQ-5D-5L index score for each category of depression severity, allowing readers to interpret the relationship between depression severity and HRQOL in the study population. The graph shows a clear decrease in the mean EQ-5D-5L index score as depression severity increases, indicating that depression is associated with lower HRQOL
