Yu Xie, a sociologist at the University of Michigan, Ann Arbor, says that although the study is methodologically sound, it overemphasizes the importance of coherent central government policies.
Only two of these studies were methodologically sound [ 30, 37].
Debarati Guha-Sapir, director of the Center for Research on the Epidemiology of Disasters, a research institution in Belgium, said that the Congo survey was methodologically sound.
We had reason to believe that both studies were methodologically sound.
Even though nearly all studies were methodologically sound, improvements are still possible in specifying whether co-interventions were avoided or comparable between the intervention and control group, and, for half of the studies, in reporting the compliance with the interventions.
However, there are few data available and the studies were methodologically varied so a cautionary note needs to be sounded and our primary recommendation is that further robust research be carried out.
While every effort was taken to ensure that the research was methodologically sound, two limitations need to be considered.
At the time, scholars said that the entire study was methodologically flawed, though subsequent research tended to confirm the findings.
The study appears to be methodologically sound: they appropriately tested the level of bias and heterogeneity among studies they included in the analysis, and they provided a separate analysis of data from studies with a low risk of bias.
The editors of this journal screen the top 100+ clinical journals and identify studies that are methodologically sound and clinically relevant.
For example, recent studies 21 22 have argued that excluding studies because of methodological flaws or incomplete reporting may result in the loss of valuable new insights, whereas studies that are methodologically sound may suffer from poor interpretation of data, leading to an insufficient insight into the phenomenon under study.
