  1. Abbreviations: CI, confidence interval; CGA, corrected gestational age; wks, weeks.
  2. Data are presented as mean±s.d., with P-values for univariate and multivariate models. Treatment effect is the average between groups difference after accounting for significant covariates, and are presented as novel teat relative to the control teat, such that negative values indicate that the occurrence in the novel teat is earlier/younger (smaller values).
  3. aThis model includes both CGA at achievement of full suck feeds and number of days to achieve full suck feeds, as both are significant without the other in the model, and lose significance together.
