Discussions with regulatory authorities gain momentum defining the role of tau biomarkers for trial designs and how they may be further qualified for surrogate marker status.
The marker status, however, remained strikingly stable.
The marker status (positive versus negative) remained widely stable.
Apart of the KLF6 expression analysis, immunohistochemical assays were performed to determine the HER2-ERBB2 aggressiveness marker status in the studied breast tumor population.
50) any of the marker status changed compared to the previous consultation (versus UC with a median of 0% of the visits (IQR 0; min. 0, max. 16.7).
The Rolling Thermal Scanner provides real-time simultaneous temperature measurements, as well as wheel position and event marker status, and a real-time graph plots differential temperature vs. travelled distance.
Provided that individual genotypes in the penultimate generation can be accurately inferred from the final generation, however, these haplotypes are sufficient for simple single marker association because analysis occurs only at the marker and does not require flanking marker status.
Considering the two samples per individual patient with the maximal changes in immune response during follow-up we next characterized the longitudinal CD patient samples for stability in marker status (positive versus negative for a respective antibody).
Given the marker status stability over time in our study, association of marker positivity with CD and certain disease phenotypes are likely to be suitable as a tool for differentiation and prediction of disease courses, independent of the time of sample procurement.
We additionally separated our cohort into two groups according to changes in marker status: "Non-status changers" (patients that did not change the number of positive markers during follow-up) and "Status changers" (patients that became positive or negative for one or more additional markers during follow-up).
Considering the follow-up time of our study we cannot recommend serial measurements, when considering the marker status and claim to use the overall immune response (QSS) with caution for disease stratification, due to strong fluctuations in a subgroup of CD subjects.
