Table 4 Multiple regressions of fruit and vegetable intake (baseline, follow-up and change) by the SCT variables (baseline and change) including the standardized regression coefficients (beta) and the semi-partial correlation (sri2).

From: Changes in accessibility and preferences predict children's future fruit and vegetable intake
