Task: Answer Verification
Input (English): Question: Are serum triglycerides , but not cholesterol or leptin , decreased in suicide attempters with mood disorders?
Answer: This is a cross-sectional study, and we cannot therefore assess whether a decrease in triglycerides caused a mood episode with suicidal ideation that led to a suicide attempt or if the presence of a mood episode originated a loss of appetite and consequent loss of weight, therefore decreasing triglyceride levels.
Output (English): yes
