This step of the methodological framework raises issues of confounding bias because not all factors that can confound these associations are measured and controlled or even known.
Table 3 shows the steps of the inclusion process: The methodological quality of the twelve included studies was then assessed by two meta-reviewers (ALF and PM) independently, with the Quality Assessment Checklist for Reviews [ 43, 44] (see Additional file 2).
This paper presents the methodological steps of the design process to contribute to the reduction of the (fine) dust problem in laying hen husbandry using the dust bath unit as an example.
In this paper, the conceptual aspects, as well as the methodological steps of the IFS were explained and further applied to one empirical case study in the Alentejo region of Portugal.
Our prior study showed that insufficient confounder selection led to high false positive rates [ 31] and therefore we designed the two-step LASSO regression (step 1 of the proposed methodological framework) to select more associated confounders.
Figure 1 Schematic overview of the methodological steps in the analysis.
For a summary of the methodological steps, see Figure 2.
The purpose of this paper is to provide a roadmap of the methodological steps necessary to create such a scoring system.
Next, we codified the procedural steps for assessing the methodological orientation and features of selected studies.
For the sake of completeness and reproducibility, we described the methodological details and the steps of the algorithm in Additional file 5. We started with a curated list of 125 known transcription factors in S. pombe with identified protein domains [ 11].
