The phrase "a prior study comparing" is correct and usable in written English.
It can be used when referring to a previous research study that involved a comparison between two or more subjects or variables.
Example: "A prior study comparing the effects of different diets on weight loss showed significant results."
Alternatives: "an earlier study comparing" or "a previous study that compared".
Consistent with this notion a prior study comparing the binding of mAb 18B7 derived chAbs revealed differences in Ag binding but the results were only strongly suggestive, since avidity contributions resulting from Ab geometry and flexibility could have influenced the types of Ab-Ag complexes formed [1].
Patient responses were compared to a historical cohort of 69 symptomatic patients recruited from the same endoscopy lists during a prior study comparing CTC to colonoscopy [ 16].
Genes positively regulated by the Gac/Rsm pathway were defined as those found differentially regulated in a prior study comparing mRNA levels of ∆ retS and wild-type P. aeruginosa (Goodman et al., 2004).
Additional evidence that the LGN was successfully excluded is supported by comparison of our results with a prior study comparing the expression of a subset of genes in LGN and MG [ 38].
A prior study comparing inputs and performance of KP and the DHS shows that KP employs fewer physicians per capita than the DHS and has a lower use of hospital beds and lower acute care admission rates than the DHS.
The only prior study comparing suicidal behavior risks among patients discontinuing lithium or discontinuing valproate observed significant increases in suicidal behavior and/or hospitalization risks among patients discontinuing either treatment [ 34].
The only prior study comparing biological acceleration between single plane ActiGraphs and Acticals has limited application as it only allowed data conversions between total daily recordings (y = 38.5 + 0.947x) and was limited to the original uniaxial model of the ActiGraph (Paul et al 2007).
Most of the differences in the number of peptides analyzed were attributed to the 1 × 10 3 OMSSA E-value criterion used in the prior study compared to the 5% FIR used in this study.
The study population was derived from a prior study that compared the implications of maternal lipids on fetal metabolism in GDM and control pregnancies (13, 14).
The results were consistent with a prior study that compared CABG cases between administrative data and registry data, which demonstrated that major comorbidities were similarly prevalent between the two data sets.
Given that prior studies comparing the performance of a single decision tree to ensemble-based decision trees have favoured the predictive ability of the latter, we believe that the ensemble-based trees will provide a more accurate predictive ability.
