Failure to assess for ascertainmentbias increases the risk of false genetic associations.
2
Background: The effect of mutations on phenotype is often overestimated because of ascertainmentbias.
3
Case ascertainmentbias from targeted PHPT screening in patients being evaluated for osteoporosis is the most likely explanation.
4
The pedigrees were influenced by incomplete ascertainmentbias, which was reduced by omitting the affected probands from the analysis.
5
High-throughput shotgun sequence data make it possible in principle to accurately estimate population genetic parameters without confounding by SNP ascertainmentbias.
1
The suggestion - predictably from a thoroughly biasedsample - was Dublin.
2
It's only fair to say that the 195 people who answered the questionnaire are a biasedsample.
3
Obviously working in the media is a biasedsample, journalists are encouraged to tweet, post or forward funny and unusual material.
4
Oh, people can always reel off lists of famous homosexual geniuses, but that's a biasedsample; of course we've only heard of the successes.
5
Previous studies of the prevalence of sleep problems in adults with intellectual disabilities (ID) are affected by small, potentially biasedsamples and other limitations.
Uso de sampling bias en inglés
1
The combined approach results in more robust reconstructions and can protect against samplingbias.
2
Sensitivity analyses showed that the conclusions are robust to samplingbias and other issues.
3
The obvious source of samplingbias there is that people desperately want to get tested.
4
Unilateral loading activities such as tennis or squash provide a direct comparison of skeletal response without samplingbias or genetic confounding.
5
They corrected for samplingbias by only considering four formations in the northwestern interior that each included more than 100 specimens.
6
Design: Analysis of survey data on mortality, adjusted for samplingbias and censoring, from nationally representative surveys designed to measure population health.
7
The current work also highlights how samplingbias can confound phylogeographic analyses and demonstrates the importance of incorporating external information to protect against this.
8
This covariation can arise from multiple factors, including selective pressures for maintaining protein structure, requirements imposed by a specific function, or from phylogenetic samplingbias.
9
Limitations: Samplingbias and the retrospective design were potential study limitations.
10
Samplingbias may have been present, in particular, in the patient panel because social media was used extensively in recruitment.
