FIGURE 3.

Raw (untransformed) survey response scores from the surveys administered in either campaign 1 (C1) or campaign 2 (C2) at HERA. Circles refer to the mean score across subjects from either campaign for each trial number. Dashed blue lines show the 95% CI range around each mean point. Solid red lines represent mixed effects linear models fit to the data within each question. β refers to the linear slope of the regression model (i.e., change in raw score per trial). Asterisks refer to significance levels after adjusting for multiple testing with the false discovery rate method with p-values referring to H₀: regression line slope = 0. (*p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001).
