Means, model estimates, and log-likelihood ratio test Chi-squared results for the mixed-effects modelling of mtDNA levels in all HIV+ and HIV- pregnant women (n = 105).

a Means (± SEM) are reported for the raw data without correction for covariates. b Estimated effects after taking covariates into account. c The modelling did not differentiate between women using 2 or more illicit drugs during pregnancy and women only taking one illicit drug. d LRT = likelihood-ratio test statistic SEM, Standard error on the mean df, degrees of freedom GA, gestational age Means, model estimates, and log-likelihood ratio test Chi-squared results for the mixed-effects modelling of mtDNA levels in all HIV+ and HIV- pregnant women (n = 105).
