Fig 11. SD of dominant direction θ (unit: rad) in different parity groups and pregnancy statuses.

Fig 11

Results from each quadrant in the outer radial zone and some combinations are shown. NP groups do not have significant differences among themselves. Between NP groups and PG, the only significant difference is found between primiparous NP and PG when P/A quadrants are combined (p = 0.004). Unlike the analysis for b, nulliparous NP (p = 0.276) and multiparous NP (p = 0.143) do not have a significant difference with PG in the SD of θ. No significant difference is found in L/R quadrants.
