Table 2 Factors influencing the likelihood of low birth weight (< 2.5 kg). Numbers (percentage), Fisher’s exact test probability and univariate common odds ratios (95% confidence intervals) are listed. Significant associations are denoted by * and are bolded. The common odds ratio greater than 1.0 indicates an association between that character and birth weight (in the sense that having normal birth weight raises the odds of having that character, relative to having LBW)
