| Explicit liking (taste ratings) | Effort provision (% of maximum handgrip strength) | ||
|---|---|---|---|
| Friedman test | Overall | χ2(2) = 7.129, p = 0.028 | χ2(2) = 15.678, p < 0.001 |
| Median (interquartile range) | Plain label | 5 (2) | 66.7 (42.8) |
| Health label | 5 (2) | 66.7 (38.3) | |
| Fun label | 6 (2.3) | 75.0 (37.9) | |
| Mean (standard deviation) | Plain label | 5.03 (1.58) | 64.61 (34.42) |
| Health label | 5.01 (1.64) | 63.28 (29.03) | |
| Fun label | 5.36 (1.45) | 72.41 (30.15) | |
| Wilcoxon test | Health label—Plain label | Z = –0.716, p = 0.716 | Z = –0.744, p = 0.457 |
| Fun label—Plain label | Z = –2.759, p = 0.005 | Z = –3.220, p = 0.001 | |
| Fun label—Health label | Z = –2.972, p = 0.003 | Z = –3.798, p < 0.001 |
Due to non-normality of data, non-parametric tests were applied. Post-hoc analysis with Wilcoxon signed-rank tests was conducted with a Bonferroni correction applied. The resulting significance level was set at p < 0.017. Bold print indicates that the respective significance level was reached.
