Fig. 4: Trend of antibiotic consumption (Day of Therapy/1000 Patient Days) of commonly used antibiotic groups between 2010 and 2020.

Each dot represents the Day of Therapy per 1000 Patient Day for each antibiotic in each year. A Loess smoothing function creates a smoothed curve through the data points and the shaded area indicates the standard error associated with the curve. The dashed line separates the periods before (2010–2016) and after (2017–2020) the implementation of the antibiotic control policy.
