Figure 4

Prevalences of each symptom of cases at designated elapsed timepoints from onset including those of each symptom at the time of answering for controls (A), and adjusted odds ratios (B) in a case–control study of long COVID, Sapporo, Japan. Reference for the regression is based on controls. The order of symptoms described is listed in descending order in terms of the prevalence of symptoms of cases at 2–3 months after onset. Age and sex are adjusted. Some odds ratios for night sweats, pleuritic chest pain, and tingling are not displayed because of nonapplicability of the regression. The definition of symptoms, which developed and persisted after onset of COVID-19 and cannot be explained by an alternative diagnosis, is only applicable to cases.
