The expression level of wolframin-stained cells per field (250x) at light microscopy was calculated and compared in different specimens by two separate observers (A.B. and F.B). in a double blind fashion and described as absent, very low, low, moderate, high, and very high.
Staining was assessed by two separate observers for each case (DS and JGK), one of whom is a pathologist.
Scoring was performed on decoded slides by two separate observers, using the following parameters.
For both VEGF and TS determinations, each section was scored by two separate observers (FDP, AMG) at light-microscope (200× and 400×) and, in cases when the difference exceeded 10%, by a third observer.
Behaviour was independently scored by two separate observers, one of whom was blind to the lesion group assignment of each animal.
T2-weighted and ZOOM-DWI images were assessed in combination for the presence of tumour by two separate observers (observer 1: 19 years experience of endovaginal MR imaging, observer 2: 2 years experience) without access to the details of previous histopathology.
To assess inter-observer variability, a random subset of 16 patients had VOIs defined on early and late scans by a separate operator blinded to the initial observer measurements and clinical data.
