Bivariate regression of in-class exam score on game choice (Table 2, Model 1: coefficient -6.29, SE 3.96, no significance star printed). The article reports the slope descriptively; no significance test or effect size is attached to this coefficient.

"The slope of the regression line indicates a negative relationship between Cooperation in the Grade Game and performance on the in-class exam, predicting that a student will score 6.7 points lower on the in-class exam if he chooses to Cooperate in the Game."
