A study aimed to evaluate the relationship between inflammatory markers and lipid metabolism in individuals with rheumatoid arthritis (RA) recruited 252 patients with RA in a tertiary care hospital. Fasting blood samples were taken for lipid profiling and for the assessment of inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate. The relationship between CRP and total cholesterol was assessed using Pearson’s correlation coefficient. A scatter plot between CRP and total cholesterol can be seen in the picture. Based on the scatter plot, which of the following can be correctly concluded about the value of the Pearson correlation coefficient, r, for CRP and total cholesterol?
