external conjugate

The external conjugate diameter of the pelvis of 1096 mothers was recorded.

The trend in cardiovascular mortality with external conjugate was abolished by allowing for head circumference.

In this study the external conjugate diameter of the mother's pelvis was strongly related to the baby's size, including head circumference.

This distance was to become known as "Baudelocque's diameter" (the external conjugate diameter of the pelvis).

In contrast the trend in cardiovascular mortality with head circumference (table I) remained significant after allowing for external conjugate diameter.

In Preston, mothers' external conjugate diameters were similarly unrelated to blood pressure after allowing for birth weight and placental weight.

Standardised mortality ratios from cardiovascular disease fell from 116 to 91 as the external conjugate diameter increased from 17 cm or less to 20 cm and over.

The babies' head circumferences correlated strongly with the external conjugate diameters, increasing by 0.17 inches (0.10 to 0.24) for each centimetre increase in external conjugate diameter.
