Weekly time series - Correlation of the two NLP models (Imaging findings NLP and COVID NLP) versus number of official COVID-19 cases per week: Temporal course on a week by week basis demonstrating the relationship between the progression and early rise of the NLP positive Chest CT studies, followed by the increase in the number of official COVID-19 cases and subsequent increase in COVID-19 deaths. There was a strong correlation with the COVID NLP when compared to the number of official COVID-19 cases on a weekly basis (r2=0.91, p<0.005).
