Cumulative Incidence functions of surgery received within 9-month after first chemotherapy for patients first treated with chemotherapy by COVID-19 period. Legend: Death (not shown) was modelled as a competing-risk event. The pre-pandemic period (dashed) is from 3 January 2016 to 14 March 2020, while the pandemic period (solid) is from 15 March 2020 to 7 November 2020. At each time point after the date of first chemotherapy, the cumulative incidence of receiving surgery was higher in the pandemic period than in pre-pandemic (Gray’s p-value < 0.0001).
