From: Face mask recommendations in schools did not impact COVID-19 incidence among 10–12-year-olds in Finland – joinpoint regression analysis

Fig. 1

Moving averages of observed 14-day COVID-19 incidences per 100 000 inhabitants (dashed line) and modelled 14-day COVID-19 incidences per 100 000 inhabitants (solid line) based on estimated average percent changes (APC) in 10–12-year-olds in Helsinki and Tampere (face masks not mandated in schools in this age group) and in Turku (face masks mandated). Dotted vertical lines indicate the time periods in which the difference in the average daily percent changes (ADPC) were calculated
