| Nutrients | Ghithaona application | 3-DFR | Correlation coefficient (r) | Difference | Limits of Agreement (LOA)& | p-value** | |
|---|---|---|---|---|---|---|---|
| Mean (SD) | Mean (SD) | Mean (SD) | Lower | Upper | |||
| Energy (kcal/day) | 1684 (622) | 1560 (520) | 0.582* | − 124 (530) | − 1163 | 914 | 0.100 |
| Carbohydrate (g/day) | 190 (71) | 179 (65) | 0.450* | − 10 (72) | − 151 | 130 | 0.229 |
| Protein (g/day) | 69 (33) | 82 (83) | 0.261* | 13 (81) | − 146 | 172 | 0.426 |
| Fat (g/day) | 72 (35) | 75 (38) | 0.551* | 3 (35) | − 65 | 71 | 0.495 |
SD = Standard Deviation.
*p ≤ 0.05 using Pearson correlation.
**p-value is the significance level between two methods using Wilcoxon signed-rank test (skewed data for energy, protein, and fat) or paired t-tests (normally distributed data for carbohydrate).
&Lower and upper Limits of Agreement (LOA) (mean difference ± 1.96 SD).
