From: Birth by caesarean section and school performance in Swedish adolescents- a population-based study
Unadjusted quantile regression modelling the association between mode of delivery and school performance. *Interpretation: the coefficient values for unassisted vaginal delivery correspond to the school grade at that percentile. Estimated coefficients for other modes of delivery correspond to the estimated difference in score at each percentile. Grey area indicates 95% confidence intervals. Note: Percentiles are recorded as proportions. For example, 0.2 corresponds to the 20th percentile etc
