Frequency of correct performance before the COVID-19 pandemic and post-lockdown in Germany, 2019–2021 (n = 726). The dotted line represents the number of medical students performing a skill correctly before the COVID-19 pandemic (Pre-SARS-CoV-2). The solid line represents the number of medical students performing a skill correctly after the first lockdown (Post-SARS-CoV-2). Frequencies are shown in percentages. Statistically significance determined by the chi-square test is marked with *. Upward arrows indicate improvement in medical students’ skills after the SARS-CoV-2 outbreak, while downward arrows indicate better results prior the pandemic
