A possible explanation for the poor agreement we observed between EtCO2 and PaCO2 during NIV could be the presence of a high airflow and of significant and often variable leaks during NIV that may have caused sampled expiratory gas dilution.
This study was performed at a single tertiary care center, which may cause sampling bias.
This caused sample D possessing large permittivity.
For some SNPs, adequate genotyping was hampered due to the inclusion of different octoploid species, which caused samples to form more than three intensity clusters.
The addition of an antifibrinolytic reagent caused samples to proceed through the first two phases immediately to the third phase and complete the whole coagulation process.
Detection of MVI using preoperative biopsy has proven unreliable owing to intratumoral heterogeneity causing sampling error.
The description of somatic variants, primarily those observed in cancer cells, includes complexities not encountered with constitutional variants, because the allele ratios are highly variable and tumor heterogeneity can cause sampling differences.
One of the difficulties of taking cores is that the drill bit can melt the ice, causing samples of different ages to mix.
Routine thin-sectioning needs equipment, it is time-consuming, expensive and cause sample wastage during sectioning.
