Probability of joint activity as a function of radiographic damage. The plot depicts the probability of tenderness as a function of JSN score at baseline. The curve was computed using logistic regression and re-scaled to a probability scale. The slope estimates the increased probability of tenderness for a unit increase of JSN score, while the y-intercept estimates the expected proportion of tender L_H_MCP2 joints in the absence of JSN (JSN = 0) among these patients. The JSN scores (0 = low,..., 4 = high) were plotted on the x-axis and tender scores (0 = no, 1 = yes) on the y-axis. *For y = 0, the patient does not have tenderness at this joint, while for y = 1, the patient has tenderness at this joint. JSN, joint space narrowing; L_H_MCP2, left hand metacarpo-phalangeal finger 2
