Semi-quantitative descriptors of contrast enhancement include onset time, initial and mean gradient of the upsweep of enhancement curves, maximum signal intensity and washout gradient.

A TTE showed severe AS with no regurgitation (maximum aortic velocity 4.3 m/sec, a mean gradient of 42 mmHg, aortic valve area <0.8 cm).

Subcategory A is defined by pathological mitral regurgitation and at least two morphological features of RHD of the mitral valve, subcategory B is diagnosed in the presence of mitral stenosis with a mean gradient of ≥4 mm Hg.

Distally, MGMT activity fell as the distance from the tumour increased with a mean gradient of −0.17 fmoles μg−1 DNA (95% CI=−1.35 1.01) but the small distal resection margins resulted in a limited number of assayable samples.

Patients were excluded if they had urgent or emergency surgery, severe aortic valve stenosis (a mean gradient of greater than 35 mmHg, and thus be at risk during exercise), limited English (which would hinder the administration of the Short Form 36-item (SF-36) Health Survey Questionnaire), or were in NYHA class IV heart failure.

The mean gradients of MGMT activity proximal and distal to the tumours were calculated and a one sample t-test, weighted according to the number of observations, used to test whether the mean gradients were significantly positive or negative.

For each auditory field the mean gradients of modulation rate and frequency preference were calculated in separate, two dimensional regression analyses as previously described in Baumann et al. (2011).

Green arrows indicate mean gradient direction of the contrast in auditory field A1 (gradient directions derived from 2D regression; see also Table 1 ).

Green arrows indicate mean gradient direction of the contrast in auditory field A1. Green circles indicate the position of the centre of mass of A1.

For directional change, we used mean gradients to apportion the quantity of change in the indicators due to fishing and the environment.
