Correlation of 16 predictors. This figure presents pairwise correlation between all predictors. Almost all predictors demonstrated linear independence from each other (with correlations less than 0.1). Some special pairs (such as age and gravidity, gravidity and scarred uterus, assisted reproductive technology and multifetal pregnancy) do exhibit certain linear correlations. However, these are easily understandable based on common sense
