In the results section under the heading “Depressive Symptoms and Adverse Events” in the last paragraph it is stated: “Labeling a response from 1–3 as a positive response, item 2 (HR: 2.05; 95% CI: 1.16–3.64; p = 0.01) was significantly associated with adverse events, and there was a trend for item 1 (HR: 1.74; 95% CI: 0.98–3.09; p = 0.06), suggesting that the relationship between depressive symptoms and prognosis was driven by both items, but to a greater extent by anhedonia.”

Instead of the last word “anhedonia” it should have been “hopelessness”.

The authors regret this error.
