For example, in a study correlating substitution rate with body mass and longevity [11], error in rate estimation would have functioned as random noise in the data; because it is not systematic, such error would not have altered the conclusions.
A study correlating biomarker modulation with pathological response may be more informative in that regard.
Shuster and co-workers reported a direct relationship between skin collagen and dermal thickness in a study correlating age and sex with skin thickness and collagen density [ 16].
There was a study correlating MR-detectable motility alterations of the terminal ileum with biopsy-documented active and chronic changes in CD.
This was supported by a study correlating the radiological OA-related changes of ankles and loss of function with increased intra-articular aggrecan concentrations [ 12].
Moreover, in a study correlating morphokinetic parameters with static morphology scoring, a CC2 less than 11.9 hours was shown to correlate with an overall increase in embryo score of 0.5 points on a 5 point scale [ 14].
Sotiriou et al. [ 21] reported a study correlating gene expression measurements generated using cDNA with clinico-pathological characteristics and clinical outcomes in an unselected group of 99 node-negative and node-positive breast cancer patients.
In a study correlating DASH to the Levine-Katz questionnaire using clinical findings and pinch and grip strength in patients with ulnar neuropathology, it was found that a high correlation between DASH scores, symptom severity and functional status of patients with ulna neuropathology existed [ 19].
A recent study correlates the presence of a vaguely demarcated scar and poorly delimited high-signal-intensity areas on T2-weighted images to β-catenin positivity [42] (Fig. 9).
