Meta-regressions—i.e., factors influencing changes in ghrelin levels following acute stress. Each variable’s effect on the outcome is represented in the forest-plot by a dot on a horizontal line. The circles represent the coefficient for each variable, and the length of each line around the dots represents their 95% confidence interval (95CI). The black solid vertical line represents the null estimate (with a value of 0). Horizontal lines that cross the null vertical line represent non-significant variables on the outcome. Bold p-value are significant.
