Intra-rater
reliability of the digitisation method involved one blinded investigator (Investigator
A) repeating digitisation on 100 randomly sampled images on two occasions. Three blinded investigators (A, B and C) analysed all 2145
images to provide comparisons for inter-rater reliability of the digitisation
method. The images were divided into images of GM (1081 images) or GL (1064
images), and reliability analyses were performed for these groups separately. For
test-retest reliability of the ultrasound image acquisition and digitisation
method combined, results were re-identified for each of the 87 participants and
separated into image number (1, 2 or 3) and test session (1 or 2). Intra-rater
between-image reliability was measured by comparing Investigator A’s results
from session 1 image 1, to session 1 image 3. Intra-rater-test-retest reliability was determined by comparing Investigator
A’s averages from test session 1 images to test session 2. The average of the
three investigators (A, B and C) results from test session 1 was also compared
against their average of results from test session 2 to determine inter-rater-test-retest reliability.
