Summary
This appears to be a research plan (not completed results) for reviewing existing studies about how certain exposures affect health. The researchers will look at both human and animal studies separately, then compare their findings to see if the results make biological sense. This type of review is important because it helps scientists combine evidence from multiple studies to better understand potential health risks.
Data synthesis and analytical framework for the systematic review. This component will include the analytical plan for synthesizing evidence from the included studies. A structured narrative synthesis will be conducted as the primary analytical approach. Human and animal studies will be analyzed separately to evaluate internal validity and methodological differences. The findings from both evidence streams will subsequently be triangulated to assess biological plausibility and potential translational relevance. Meta-analysis will be conducted when at least three studies report comparable exposure-outcome relationships and methodological characteristics. Random-effects models will be used to account for expected heterogeneity. Statistical heterogeneity will be evaluated using the I² statistic. If heterogeneity exceeds 75% or if studies are not sufficiently comparable in terms of exposure assessment, outcome measurement, or study design, only narrative synthesis will be performed. Subgroup analyses may be conducted according to species (human versus animal), sex, type of exposure, pesticide class, microplastic characteristics, and biological matrix analyzed.
