Findings were based on repeated measures analysis of variance; baseline scores were used as covariates. Although a trend toward greater improvement in the greens+ group was noted in the other secondary outcome measures, this trend did not reach statistical significance. Overall, our findings were positive but not conclusive that greens+ increases vitali...Continue Reading
