For each landmark (3, 6, and 12 months), survival is conditional on patients being alive at the landmark. Symptom level classification is based on an individual’s most recent symptom score prior to the landmark time. Symptom levels for PHQ9 are 1–7 (none/mild), 8–14 (moderate), and 15–27 (moderately severe / severe), with higher scores indicating worse symptoms. GAD7 symptom levels are 0–4 (none), 5–9 (mild), and 10–14 (moderate) and 15–21 (moderate/severe), with higher scores indicating worse symptoms. The number at risk in each symptom group is indicated in the bottom corner, left, of each figure.
