For the studies on the energy payback time and greenhouse gas footprint of PV module production, it is sometimes difficult to ascertain in retrospect whether the studies were performed using a consistent method, especially for the older studies selected here.
Using a consistent cut-off in both studies also increased comparability between them as continuous distributions were likely to differ between the two cohorts.
All men received antibiotic prophylaxis according to contemporary practice; inter-centre variability existed, but each centre used a consistent schedule throughout the study period.
The study used a consistent set of primary care quality indicators over the entire study period and employed longitudinal panel data estimation, therefore improving the robustness of results compared to previous research.
The present follow-up genome scan, which used a consistent research design across studies and examined the largest ASD sample collection reported to date, gave either equivalent or marginally increased evidence for linkage at several chromosomal regions implicated in our previous scan but eliminated evidence for linkage at other regions.
In this study, we used a consistent set of in vivo experimental protocols to study three typical nanomaterials that are characterized by particle size, shape, and chemical composition: single-walled carbon nanotubes (SWCNTs), silicon dioxide (SiO2), and magnetic iron oxide (Fe3O4) nanoparticles.
This particular study used a consistent model for comparing the two subduction zones; however, one cannot necessarily assume that tectonic tremors will occur at the same temperature in all subduction zones because there may be other specific environmental differences between them that are important in terms of modeling their individual thermal structures.
The present study used a consistent and reproducible method to measure drug-induced PLD for an immortalized, quickly proliferating cell line.
Furthermore, it will be important for future studies to use a consistent and appropriate definition of TSP, and specifically avoid using simply 'back pain' as an outcome variable, a recommendation endorsed by a recent international consensus [ 29].
Programs in the study do not use a consistent targeting methodology.
