Given the fact that few genes are sampled very completely across many taxa, supermatrix methods often sacrifice completeness in the interest of size.
Three questions, however, presented a very low completeness.
The NRYPMDR has very good completeness and ascertainment (>98%%) [ 40].
Conversely, larger population registries tend to have very stable completeness indices because of large case counts.
Pedersen et al 7 showed a very good completeness of 94% of hip arthroplasty registration from 1995 2000 in the Danish Hip Arthroplasty Register.
The session-by-session monitoring was successful with both demonstration sites achieving very high completeness levels for their pre- and post-treatment assessments.
Conversely, larger population registries, which tend to have very stable completeness indices because of large case counts, may be penalized for an apparent lack of progress.
Sample attrition due to missing sociodemographic or cancer diagnosis information was trivial, given the very high completeness of this information in the primary sources used in the Routes to Diagnosis project.
Information on laterality of amputations was also available in this study with very high completeness, enabling identification of LEAs on different limbs during the same admission, and these procedures could be counted separately.
7, 16, 22 A study from the Norwegian Registry of Knee Ligament Reconstruction reported a very high completeness (86%) when using hospital protocols as a reference standard and 84% when using the Norwegian National Patient Registry as a reference standard.
