Fig 1 — Weight loss and SEFI trajectories during the course of COVID-19 infection and recovery period (N = 403 patients). Weight loss and SEFI trajectories at t0 (before disease), t1 (in the course of COVID-19), and t2 (recovery period at 1 mo); uncomplete trajectories (i.e., with missing values) are displayed as shorter segments or as dots. Weight loss values (as a percentage of weight at t0) were grouped into classes: none: <5%, medium: [5%; 10%], and severe weight loss: ≥10%. Weight loss at t0 was 0 for all patients. Food intake values were grouped into classes: normal: [0, 3], low:³^,⁷, and very low food intake:⁷^,¹⁰. SEFI at t0 was assumed to be 10 for all patients. SEFI, Self-Evaluation of Food Intake.
