The analysis included a total sample of 1668 participants. Authors estimated effect sizes as standardized mean differences using Hedges' g with small-sample correction. Results were pooled using a DerSimonian-Laird random-effects model.

The pooled effect of nutrition counseling on quality of life was SMD 0.71, with 95% confidence intervals from 0.35 to 1.07. The finding reached statistical significance at p < 0.001.

Substantial heterogeneity was observed across included studies. Reported I² was 88.7%.
