Based on the best-case scenario for the same missing observations buy cheap benzac 20 gr online, the direction and size of the effect of the intervention changed to –0 buy 20gr benzac with visa. Therefore generic benzac 20gr without prescription, neither scenario provided any tentative evidence of a significant or meaningful intervention effect (see Table 9). Subgroup analyses of body mass index standard deviation score at 24 months The results for the prespecified subgroups, defined by gender, school size, free school meal category and cohort, are presented in Table 10. The estimated intervention effects were small and in the same direction within subgroups for gender, cohort and school size, with little or no effect on the BMI SDS at 24 months and no evidence of a significant difference from the null effect. Interaction terms between each factor and the allocated group were added to the random-effects model, and the absence of modifying effects by each factor was confirmed by results from the test of the interaction term. Similarly, there was no evidence of a modifying effect on the intervention by the BMI SDS at baseline or from the individual child-level IMD scores. The point estimate for the effect of the intervention in either level of the free school meal factor was not significantly different from the null, but, although this effect was negative in those schools with < 19% of their children eligible for free school meals, there was a small, non-significant, increase in the BMI SDS in those children from schools in which ≥ 19% of pupils were eligible for free school meals.

As noted in Chapter 2, these subgroup analyses, although prespecified, are considered to be exploratory and the trial was not designed with the aim of being able to detect differences between subgroups. Longitudinal analysis of body mass index standard deviation score The analysis was based on fitting a longitudinal model with observations at fixed time points (baseline, and 18 months and 24 months post baseline). The complexity of the between-time-point covariance for each child was reduced to an autoregressive pattern of order one. As the outcome of this longitudinal model comprised all BMI SDS measures, including those at baseline, the effect of the intervention was determined from the interaction between the allocated group and the time point. According to this model, there was no significant difference between the two groups at baseline (intervention BMI SDS greater than controls by 0. The BMI SDS increased significantly in both groups at each subsequent time point relative to baseline, by an average of 0. Figure 4 shows the predicted marginal BMI SDS by allocated group across the time points of the trial. According to the longitudinal model, allowing for hierarchical clustering by child within each school, modelling the within-child covariance between fixed time points as an autoregressive pattern of order one.

RESULTS (PRIMARY AND SECONDARY OUTCOMES) Primary analyses of secondary outcomes at 24 months (anthropometric measures only) Table 11 shows the summary data of the remaining anthropometric measures at 24 months post baseline. Among the children in the intervention group, slightly more were classified as being overweight or obese, according to the Public Health England definition of categorisation of BMI scores at 24 months, relative to the control group (30. However, analysing the weight status categories under the assumptions of an ordinal logistic model with school-level random effects, there was no evidence of an intervention effect in the fully adjusted model (p = 0. The odds of being in the higher weight categories were greater among the children in the intervention group than among those in the control group, although this change in odds was not statistically significant [odds ratio (OR) 1. The intervention effect size was similar in both the unadjusted and adjusted models. Relaxing the assumption of proportional odds, the estimated intervention effect size from the generalised ordinal model, with a robust error variance clustered on schools, was comparable with that from the random-effects ordinal logistic model (results not shown). The test of proportional odds under the Peterson–Harrell parameterisation indicated that there was no evidence of a change in the odds between binary comparisons of levels of weight status category (p = 0. Consistent with the primary outcome measure, the average anthropometric measurements were generally slightly larger for the children in the intervention group at 24 months, as they were at baseline, relative to those in the control group (see Table 11).
