The phrase "and compared the frequency" is correct and usable in written English.
It can be used when discussing a study or analysis that involves examining and contrasting the occurrence of certain events or data points.
Example: "The researchers collected data from various sources and compared the frequency of occurrences across different demographics."
Alternatives: "and analyzed the frequency" or "and evaluated the frequency".
We next annotated A (active) and B (inactive) chromatin compartments1 and compared the frequency of interactions between bins belonging to the different compartments in normal and CBL0137-treated cells.
Accordingly, we have tested whether this gene is associated with susceptibility to CML development, and compared the frequency of this haplotype between CML and healthy control groups using the data previously published (Supplementary Table 5).
We also normalized these numbers by the total length of the corresponding databases (i.e. the frequency of In100-elements) and compared the frequency of In100-elements in the simulated database with the one observed in the human genome.
For this purpose, we introduced 3.0 pg of sgRNAs and 30 pg of Cas9 mRNA, and compared the frequency of normally developed larvae with that of uninjected controls.
We analyzed comorbidity rates within a subset of 1,368 individuals carrying specific deletions and duplications associated with genomic disorders and compared the frequency of comorbid features in boys and girls.
Using the same TNR- and variant-encoded protein sets as above, we classified homo-AA proteins by the repeated residue and compared the frequency and length of residues between the sets.
Having confirmed the distinctiveness of the disease sample, we pooled the 147 isolates from the five kindergartens and compared the frequencies of the genotypes of all carriage isolates with the 51 disease isolates.
To assess this possibility, we sampled cryopreserved peripheral blood mononuclear cells (PBMC) from 20 HIV controllers, 20 ART-suppressed, and 20 untreated non-controllers, and 34 healthy HIV uninfected controls and compared the frequencies of CD25+CD127dim CD4+ Tregs between groups.
Due to the low allele frequencies of rare variants, and findings reported for TLR4 in patients with meningococcal infection [18], we pooled all rare NSPs within each TLR and compared the frequencies of rare alleles between cases and controls in each ethnic group (Table 2).
Except Arg587Arg SNP, the frequencies of other 17 polymorphisms were inferred lower than 1%, and we pooled all the rare variants and compared the frequencies (Table 2).
Previous study has explored and compared the frequencies of 20 nature amino acids among the 4 types of J-proteins, whindicatesathatthet the frequencies of the 19 nature amino acids are remarkably different [ 14].
