The phrase "age were investigated using" is not correct in written English.
It appears to be a fragment and lacks clarity, likely due to a missing subject or context.
Example: "The effects of age were investigated using various statistical methods."
Alternatives: "age was examined using" or "age was analyzed using".
Receipt of surgery by age was investigated using logistic regression, adjusting for co-morbidity and other patient, tumour and treatment factors.
Key: PMM = predictive mean matching; MI = multiple imputation The applicability of the linearity assumption for age was investigated using fractional polynomials [ 23], fitted using the 'fp' function within the 'mfp' library in the R statistical software [ 24].
Age-hardening behavior, microstructure evolution and its influence on mechanical properties of the alloy during aging were investigated, using X-ray diffraction, transmission electron microscopy, tensile and hardness measurements.
The shape of a coherent rhombohedral precipitate in a cubic matrix and its growth and dissolution during strain-constrained aging were investigated using a time-dependent Ginzburg-Landau kinetic model by taking into account the coupling between the constraint (applied) strain and the local strain.
Differences between mean EQ-i scores and proportion of males/females, ages, were investigated using t-tests and chi-square analysis and none were found (Table 1).
Ten cadaveric lower limbs from 7 specimens, three paired and four unpaired (5 men and 2 women; mean age at death 78 years) were investigated using macro dissection techniques.
The precipitation process in a wrought PH13-8 steel during ageing was investigated using a position sensitive atom probe.
The genetic program that determines life span and aging is investigated using models of different species, including yeasts (Saccharomyces cerevisiae), worms (Caenorhabditis elegans), insects (Drosophila melanogaster), and mammals (Mus musculus) [1].
Pore segregation during ageing was investigated using the microfluidics dissection platform (Lee et al., 2012; Huberts et al., 2013) with constant flow of synthetic complete medium at 1 μl/min and an Eclipse Ti fluorescent microscope (Nikon Instruments) controlled by Micro-Manager 1.4 software (μManager).
The effects of model prior designations on age estimates were investigated using runs that exclude the nucleotide data [ 53].
