Fig. 4: Raincloud plot showing sensitivity to matching pairs of labels and shapes, compared by trimester.

Nulligravida n = 102, 1st trimester n = 36, 2nd trimester n = 35, 3rd trimester n = 29. 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.
