Association between PTX3 level and time of pre-eclampsia onset in the pre-eclampsia and HELLP groups. OR indicates the change in the odds of having early, intermediate or late pre-eclampsia (a) or HELLP syndrome (b) conferred by each one-unit increase in PTX3 level. Adjusted for maternal age, ethnicity, recruitment place and date, low socioeconomic position, familial history of pre-eclampsia, smoking, BMI and multiple pregnancy. Gestational age was not included in the model because this variable defined the subphenotype assessed. OR from multinomial logistic regression for pre-eclampsia (All PE) and HELLP Syndrome (All) are included only for comparison purposes. Odds ratios are reported on a logarithmic scale
