Furthermore, sex differences and sex by strain interactions are not uncommon across studies of the BXD strains [62], [63], [64].
Paradoxical results are not uncommon in studies of carcinogenesis.
Poor compliance is not uncommon in studies of non-surgical treatments [ 40].
It is not uncommon that studies of the same type of TKA or THA report rather different revision rates [ 31].
Since biliary tract cancer is an uncommon disease, studies of chemotherapy for biliary tract cancer are relatively few, and the number of included patients is generally small.
Acute myeloid leukaemia (AML) with central nervous system (CNS) involvement in adults is uncommon, and studies of this subject are scant.
We also have not assessed disease-specific mortality in this analysis, instead using all-cause mortality, which would not be uncommon in studies of advanced disease.
For instance, it is not uncommon for studies of occupational exposure to use previously-collected data to investigate a new research questions; for instance for studies of sampling strategies [ 11, 13, 21, 24].
This is not uncommon in studies of patients with schizophrenia and, nevertheless, the effect size data for paliperidone palmitate compared to placebo suggests a clinically meaningful dose- and time-dependent treatment effect in this population.
Analysis of absolute allele-specific copy numbers is uncommon in studies of this kind; copy number gain and loss are normally assigned based on log-ratio only (DNA abundance in the extract, along the reference genome, relative to its own median [ 11]), disregarding tumour cell content and unknown average ploidy of genomes.
