an increasing trendP < .001
Linear regression revealed an increasing trend of combined shoulder and elbow injuries (slope = $22.35 million/year, R 2 = 0.786, P < .001; Figure 1 ), elbow injuries (slope = $17.93 million/year, R 2 = 0.628, P = .006; Figure 2 ), and shoulder injuries (slope = $4.41 million/year, R 2 = 0.422, P = .042; Figure 3 ).
