Cohort of women in the fertile reproductive life stage at the SCI
event
Descriptive statistics were provided for demographics and injury
characteristics and grouped by reproductive behaviour. Univariate and
multivariable logistic regression analyses were performed to calculate
unadjusted and adjusted odds ratios (OR) of the likelihood of becoming a
mother after the SCI event with selected predictive variables: age at
injury, level of education, injury level and completeness, and birth
country. To account for item nonresponse (i.e., missing items of
predictive variables for a subset of participants), a random forest
imputation technique was used with the assumption that data were missing
at random (11). For women who became
mothers after the SCI, the timespan between the age at injury and the
first delivery was displayed by cross plotting the age at injury and the
age at delivery of the first child. Moreover, the ages at the first and
second deliveries after the SCI were cross-plotted. The data analyses
were conducted using R version 3.5.0.
