Maternal weight gain during pregnancy. A. Comparison of maternal gestational weight gain in GW1, GW2, GW3 and Control mothers. The figure shows the results of one-way ANOVA of weight by maternal group. The side points of each diamond are connected by a horizontal line at the mean of each group. The top and bottom diamond points are the upper and lower 95% confidence points of each group. B. Comparison for all pairs of means of maternal gestational weight gain using Tukey-Kramer (HSD). The Tukey-Kramer (HSD) added comparison circles to the plot and statistically compared each pair of means. There is a circle for each group with a horizontal diameter that aligns with its group mean. Circles with the same color are not statistically different while those with different colors represent groups with statistically different means.
