Of several focal details notably synchronised which have sex and you may years

We calculated correlations off redheadedness and you will yields details having sex and you will possibly confounding parameters (many years, sized place of home, current sexual relationship standing, real situation, and you can mental disease).

In our dataset, ten (nine.2%) feminine and you will five (5.5%) dudes stated they had not yet had the basic sexual intercourse. We have for this reason did a great Cox regression to provide the result of them sufferers. Redheadedness (as the an excellent linear pattern) displayed a serious affect the probability of with very first sexual intercourse (Hour = dos.527, p = 0.002). There was and additionally a serious self-confident quartic (^4) spline about model (Hours = 2.580, p = 0.003), suggesting that the relationship ranging from many years to start with sexual intercourse and you may redheadedness wasn’t linear and increased which have an advanced level out of redheadedness.
