Fig. 3: Sensitivity to matching pairs of labels and shapes, compared by group and shape-identity.

Nulligravida group boxplot and individual markers on the left, and primigravida group boxplot and markers to the right for each identity. Boxplots depict median value (centre bar), 25% and 75% interquartile range, and outliers lying beyond the ends of the bars, which represent the most extreme datapoint, which is no more than the range times the box width per standard R boxplot code.
