| Short‐term impact (< 12 months) child fruit and vegetable intake | The mean short‐term impact (< 12 months) child vegetable intake frequency score was 4 (a score of 4 corresponds to consumption of vegetables 3 ‐ 4 times per week) | MD 0 | ‐ | 238 (1 RCT) | ⊕⊕⊝⊝ LOW 1 2 | The only study (Baskale
2011) reported an increase in some of the fruits
and vegetables assessed in the intervention group and no
significant differences in the control group The duration of follow‐up post‐intervention was 8 weeks |

| *The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval | ||||||
| GRADE Working Group grades of evidence High quality: We are very confident that the true effect lies close to that of the estimate of the effect Moderate quality: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different Low quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect | ||||||
1Downgraded one level for risk of bias: high risk of bias due to lack of blinding and loss to follow‐up. 2Downgraded one level for imprecision: total sample size < 400.
