As the PEP-CTERM domain is probably too small to carry enzymatic activity or direct binding to a small molecule , the conservation of the nearly invariant Pro-Glu-Pro motif most likely reflects a physical interaction with another protein . The NTERA-2 line also has advantages for antibody-based comparisons , as the line is well adapted to culture and grows quickly without feeder layers , attachment matrices , or the addition of any specialized growth factors other than serum . The data are presented as percentage change in the fluorescence intensity at each time point ( F ) to the first time point ( F0 ) reading ; the term ( ( F - F0 ) / F0 ) 100 was used to represent this percentage change . Use of treatment episode as the unit of analysis may create bias , because 1 patient may have been initiated on several medications over time , thus contributing multiple episodes . In another recent study [ 41 ] , our group conducted a post hoc analysis of time to all-cause medication discontinuation using data from a 1-year , randomized , open-label study of schizophrenia patients treated with olanzapine , risperidone , or typical antipsychotics .
