Sentence examples for given birthweight from inspiring English sources

20 Where the number of studies reporting a given birthweight standard and outcome allowed, we performed subgroup analysis to examine the effect of potential confounding factors.

For a given birthweight, South Asian babies born in India have been found to be fatter (as measured by subscapular and triceps skinfolds or cord-blood leptin levels) than white European babies born in Europe or the USA [ 7– 9].

We address a number of methodological issues related to our proposal, including the construction of confidence intervals for mortality risk at any given birthweight within a component, for odds ratios comparing mortality within two different components from the same population, and for odds ratios comparing mortality within analogous components from two different populations.

The charts currently used in Scotland are based on data from the 1970s and require updating given changes in birthweight and in the measurement of gestational age since then.

Given that the birthweight of Pakistani infants was >250 g lower than that of white British infants, this difference highlights a very different body composition between the two ethnic groups.

For example, Leonard, et al. (2007) [ 16] and Hutton, et al. (2007) [ 17] used the ratio of the observed birthweight to the expected birthweight for a given gestational age to assess fetal growth, whereas Leitner, et al. (2007) [ 15] and Gortner, et al. (2003) [ 19] classified all infants with birthweights below the 10th percentile as small for gestational age at birth.

The old 250-gram variable tended to underestimate the weight of children with a birthweight lower than the mean, as expected given the approximately normal distribution of birthweight.

However, testing the significance of a quadratic term for birthweight gave nonsignificant results, P=0.21.

We also felt that there was too much potential for confounding to examine the association between birthweight and stillbirth, given that stillbirth may occur days or weeks prior to delivery, and therefore lead to the inclusion of premature infants in the analysis.

A forest plot of the summary meta-analysis odds ratios and 95% confidence intervals for each measure of fetal growth restriction in relation to neonatal mortality is given in Figure 2. A birthweight below 1.5 kg showed the strongest association with neonatal mortality (OR 48.6, 95% CI 28.62 82.53), with no between-study heterogeneity in this effect.

Newborns classified as small-for-gestational age (SGA) were defined by a birthweight lower than the 10th percentile of birthweight distribution for a given gestational age and sex, according to French reference curves [ 22].
