Differences between the patients with SARS-CoV-2 and the control group. (A) Slow component of VO2 (VO2SC) during the constant-load test at the intensity of the first ventilatory threshold (VT1). (B) Mechanical efficiency (ME) during the constant-load test at the intensity of the VT1. (C) Ventilatory efficiency during incremental cardiopulmonary test. (D) Ventilatory efficiency during the constant-load test at the intensity of the VT1. Data are given as mean and error bars correspond to 95% confidence intervals (95% CI). ★ The patients with SARS-CoV-2 increased the VO2SC (p < 0.01) and the VE∙VCO2–1 slope (p < 0.001), and decreased the mechanical efficiency compared to the healthy control group (p < 0.05).
