In this analysis, TDEs include three distinct surrogate endpoints; TTP, PFS, and EFS.
These alternative approaches are rarely suitable for adjusting (normalizing) for analyte losses during sample preparation and detection, because of potentially very different chemical and physical behaviors of the target and its structurally distinct surrogate, however.
The newly identified mechanism antigen processing, leading to T cell induction, appears to be distinct from surrogate antigen processing and peptide secretion described previously [41], but appears analogous to trogocytosis [24], and possibly to cross-dressing [42].
Figure 2 shows the results, with the sample acf shown for lags 1 to 6. Seven of the eight time series are distinct from their shuffle surrogates, showing that they have some serial correlation.
Two fundamentally distinct secondary tasks (or surrogate in-vehicle information systems, sIVIS) were developed: a visual search task, designed such that it only required visual processing/demand and an auditory continuous memory task, intended to cognitively load drivers without any visual stimulus.
While the strategies above could be easily implemented, overly simplified conversion to surrogate categories may lead to loss of information, and the resulting estimates corresponding to surrogates or proxies have distinct interpretations than the ones corresponding to individual exposures.
The distinct advantage is that trials with surrogate end points require fewer patients, require shorter follow-up, are less expensive, and facilitate drug development.
These issues are quite distinct from the strength of evidence of a surrogate, the aim of the STE and BSES.
Analysis of breast tumours revealed nuclear ERβ immunoreactivity, but there were no associations with known clinical prognostic markers, highlighting the fact that ERβ may have a distinct biological role and is not just a surrogate for ERα.
However, even though WFA+-M2BP can be considered a surrogate marker for liver fibrosis, a distinct advantage of WFA+-M2BP over liver biopsy is its wider dynamic range for the evaluation of liver cirrhosis.
Here, we established an intrathecal infection model with VV and used this system as an in vivo surrogate to correlate the access of distinct T helper cell subsets with successful host defense.
