With the same refractive index and viscoelastic parameters of the vitreous, as well as good biocompatibility, it seemed to be a valid long-term substitution.
Maybe there are some very valid long-term reasons?
The constant advances of adhesive materials jeoperdize the execution of valid long-term clinical studies, demanding evidence from in vitro studies that simulate the oral conditions [16].
However, valid long-term outcome studies with sufficient patient numbers are lacking [ 10, 11].
These studies fulfill all the main requirements for obtaining a valid result: long-term follow-up (∼5 years), a large cohort of diabetic patients, retinopathy assessed by standardized methods, and a significant number of patients without diabetic retinopathy at study entry, thus allowing evaluation of the effectiveness of prevention.
In the context of a real network, the key findings of the article should be valid in long term, i.e., assuming averaging of the traffic load conditions due to user mobility and variation in time.
Such a strategy is still valid in the long term, but could be problematic in today's uncertain economic climate.
The results of the validation study indicate that the food frequency questionnaire provides reasonably valid measurements for long term dietary intakes of common foods, macronutrients, and common micronutrients.
Other projects were directionally valid over the long term; Guyana and Venezuela, for example, produce substantially more gold today than when Operation Goldfinger was eying them in the late nineteen-sixties.
"Nature conservation is a long term thing.
This is a long-term project.
