Beta regression coefficients (<i>t</i>-statistics in brackets) for analyses predicting maternal instrumental care duration.

NOTE: For Tables 3 and 4, coefficients represent averages from ten imputations; the ‘full model’ contains several maternal and infant covariates whereas reduced model (obtained after F-test reduction in number of predictor variables) contains only variables that contribute significantly to the model. ∼p<0.10, *p<0.05, **p<0.01.
