More rigorous study is needed, including longitudinal observations, direct exposure assessment, and chemical characterization of VOCs and secondary pollutants in homes' indoor and outdoor air.
For a more rigorous approach, methods of holding out several observations will have to be explored.
This observation needs to be confirmed in more rigorous studies.
But like all anecdotal evidence, on-the-water observations need to be backed up by more rigorous scientific research.
Such observations are encouraging and warrant further and more rigorous studies to assess potential adverse effects on the embryos caused by OET assay.
Shen et al. share the observation of Albuquerque et al. that more rigorous research of the field is needed.
Locus-wide comparisons suggest that the transferability might be even more extensive, but more rigorous analyses with larger samples will be required to establish these preliminary observations more firmly.
The observation made by Albuquerque et al. is shared in that a more rigorous research is needed.
The minimalists were more rigorous.
So was adjusting to more rigorous competition.
There are more rigorous performance standards.
