Schematic representation of the difference in the dispersion of collagen fibres based on menopausal status. Quantitative comparison of collagen alignment between premenopausal and postmenopausal cervical samples measured in degrees. The bars represent the mean difference in deviation for pre- and postmenopausal groups respectively (in absolute values) which is statistically significant with p < 0.01. Error bars indicate 95 % CI interval confidence for the mean difference in dispersion
