In any case when a paper reported different results in different population groups analyzed, in different study periods, or according to the type of dependent variable analyzed, this was described as a relationship that "varies depending on another variable".
Morphological features were analyzed in different ways in the two studies.
However, in these studies, methylation levels were not analyzed in different stages of plant development.
It has to be noted that for LOH measurements of each patient sample pair of normal and tumor tissue, the same tumor DNA isolation samples were analyzed in different assays taking in account of tumor heterogeneity, including the case SK-22 analyzed in a different time in a different study by microsatellite marker D3S1611.
Moreover, the differences between the different studies might also be related to the size and characteristics of the patient cohorts analyzed in the different studies.
In addition, the wide range of outcomes analyzed in the different studies make it almost impossible to get a good general idea of the efficacy and effectiveness of CBR.
In all of these studies, the variability of antibiotic doses administered is striking; this, on the one hand, reflects the uncertainty of the clinician on how RRT may affect antibiotic concentrations but, on the other hand, adds a level of complexity when it comes to analyzing target attainment in different studies.
The wide variation of liver transaminases in our patients cohort could lead to higher transient elastography values and consequently to higher cut-off, as noted in different studies analyzing correlation of TE with liver fibrosis [ 21].
It is possible that the wide variation in the extension of lymphoid aggregates in different tissues, and the different histologic criteria used to identify LN may explain the variable associations of LN with molecular markers and disease severity found in different studies analyzing lymphocyte aggregation and organization [ 22].
Secondly, there has been a study on 155 knee prostheses of various types, which were included in different studies and then analyzed retrospectively when 12 of them had been revised for loosening (Ryd et al. 1995).
