What is difference between ( relative ) and (absolute) contraindication

what is difference between ( relative ) and (absolute) contraindication

If a woman has an Android pelvis totally inappropriate for NVD, it’s an absolute contraindication for NVD. But if the pelvis is contracted, with the interspinous diameter of 10cm (which is minimum requirement) we can do trial of labour, so it becomes a relative contra indication.

For an explanation like that, u could have written “thank you” fully instead of “tq”
