The phrase "a baseline difference in" is correct and usable in written English.
It can be used when discussing a fundamental or initial difference between two or more subjects, often in research or analysis contexts.
Example: "The study revealed a baseline difference in the performance levels of the two groups before any interventions were applied."
Alternatives: "an initial difference in" or "a fundamental difference in".
This could cause selection bias and a baseline difference in resistance to antibiotics between groups.
However, a baseline difference in the prevalence of cerebrovascular disease and chronic obstructive pulmonary disease was identified (Table 1).
31 In addition to the lack of information about random sequence generation, blinding, and other useful information, a large portion of studies did not assess the antibiotic sensitivity or resistance of H pylori. Thus a baseline difference in resistance to antibiotics between groups cannot be ruled out.
Within this framework, a baseline difference in wagering criteria may be caused by the variance of the signal (word) distribution being greater than the noise (non-word) distribution, leading to a more prominent f(I| x) distribution following non-word responses and requiring more conservative criteria to maintain a given level of wagering performance.
Although there was no statistically significant difference in white blood cell counts or a baseline difference in immunosuppression or chronic steroid use, we did find that obese and overweight patients expressed significantly lower plasma IL-6 levels during the initial phase of septic shock compared with those with a BMI of less than 25 kg/m.
Comparison 4 addresses the clinical question "Does treatment effect differ between the g+ and g− subgroups?" However, this analysis is not a randomized study; also, the observed difference between the two subgroups may be associated with a baseline difference in the control arm, Comparison 5.
Section 4 presents the empirical results including a sample description, the baseline difference-in-differences results, robustness checks, and effect heterogeneities with respect to sectors, types of training, the employees' financial participation at training costs, and training by qualification levels.
O2 delivery was proportional to LBF, and a small difference in baseline LBF was reflected in a baseline difference of O2 delivery (P = 0.14).
There was a large baseline difference in the characteristics of the group receiving acid-suppressing medications versus those patients not receiving the medications.
Interestingly, there was a significant baseline difference in the amount of time invested in study between the non-users, moderate users and intensive users, which could represent an important confounding factor for the examination grade as it suggests that the users of the app are in general higher achievers compared to the non-users.
This corresponded to the shorter allele (19 kb vs. 87 kb) as desired; however, in the absence of genotyping data, a known baseline difference in methylation between 4qA and 4qA-L alleles could be adjusted for in deciding which should be regarded as the less methylated allele.
