Meta-regression of total exercise dose and improvement in sleep quality.
Scatter plot with bubble sizes representing sample sizes, showing the relationship between total exercise dose in hours and BMI mean change. Blue line indicates a linear trend and red dashed line shows a quadratic fit, with shaded confidence intervals around each. Quadratic fit suggests greater reduction in BMI occurs with moderate exercise doses, with increases at higher doses.
Meta-regression of total exercise dose and improvement in BMI.
Scatter plot showing the relationship between total exercise dose in hours and effect size as mean change, with data points represented by circles of varying sizes. The plot includes a solid blue line for the linear model and a dashed red line for the quadratic model, each with shaded confidence intervals. Both models show little association between exercise dose and outcome, with P-values of 0.68 and 0.826, respectively.
Non-linear dose–response relationship between total exercise dose and improvement in BMI.
Scatter plot illustrating a non-linear dose-response relationship between total exercise dose in hours and BMI mean change, with a red dashed quadratic regression curve and shaded confidence interval showing optimal dose around 60 hours.
