Factors associated with persistent post-COVID-19 condition and functional limitation four years after SARS-CoV-2 infection | Scientific Reports / Initial survey (phase I)

"Participants provided informed consent electronically before starting the questionnaire. The questionnaire enquired data on demographics (sex, age, ethnicity, height and weight), comorbidities, blood group, COVID-19 severity according to the World Health Organization (WHO) clinical progression scale13, therapy, vaccination status, and a wide range of acute and persistent symptoms (neurological, psychiatric, cardiovascular, pulmonary, abdominal, musculoskeletal, endocrinologic, and others). Furthermore, current restrictions in daily life were also assessed using the PCFS scale12 and additional information on reasons for SARS-CoV-2 testing, probable source of infection, and timing of infection and vaccination was requested."
