For this reason, the stronger link does not take advantage of its good channel conditions to improve the overall transmission rate, which lowers the validity.
This may lower the validity of our findings.
The lack of a definite start and end point of physical activity lowers the validity of data on calculated average steps per hour.
This ambiguity of what is measured may lower the validity of the item and scale when used by sexual minority respondents.
They also mentioned that even since 1936 when Welch stated that no Widal test, regardless of the composition and standardization of the antigens used is infallible, and thus it is unlikely that any will be developed that will lower the validity of the isolation of the etiologic agent.
In our study, the clinical classification of soft tissue shoulder disorders and use of strict inclusion criteria lowered the external validity with respect to the 312 patients considered for inclusion.
Furthermore, previous studies with objectively measured physical work demands are limited by short and often selected time windows [ 26- 28] or measurements of physical demands in laboratory environments [ 18, 29, 30] lowering the external validity.
Although selecting reviewers according to the principle of complementarity (for example, choosing a generalist and a specialist) will lower IRR, the validity of the process can gain, according to Langfeldt [94]: "Low inter-reviewer agreement on a peer panel is no indication of low validity or low legitimacy of the assessments.
A cohort study is used to estimate risks, rates or occurrence times of events, and thus requires that the whole cohort remain under observation for the entire follow-up period. 2 Loss of subjects during the study period lowers the validity of the study, because it makes estimation more difficult due to unknown outcomes of lost subjects.
This can potentially lower the validity of the results, but since the definition of an outcome does not change within the trial, it is not likely to substantially affect the results in favour of any of the groups, and it may still be used to see a trend.
