Table 3 shows the means and P values for the differences in the gradients of plots of mean common carotid intima-media thickness against age for most deprived and least deprived men, adjusted as described for each model.
To calculate the TEAC, the gradient of the plot of the percentage inhibition of absorbance versus concentration plot for the extract under investigation is divided by the gradient of the plot for Trolox [ 52].
To calculate the TEAC, the gradient of the plot for the sample was divided by the gradient of the plot for trolox.
The fact that the gradient of the plot of S100A4 against motility is about five times that of the plot of S100A4 against invasion suggests that the same cells are having to penetrate a more resistant barrier.
To calculate the TEAC, the straight line gradient of the plot for the sample was divided by that of Trolox (Additional file 1: Figure S1).
The gradient of the plot, which represents tissue FDG clearance (Ki), was divided by the intercept, which represents tissue distribution volume of FDG (V 0)—see Eq. 3).
The value of the second-order rate constant can be found from the gradient of a plot of ln removal of the target compound against the time-integrated oxidant concentration.
These are manipulated in a similar manner to that conventionally employed with (uniaxial) creep test data, allowing the stress exponent, n, to be obtained as the gradient of a plot of the logarithm of the equivalent strain rate against the logarithm of the equivalent stress.
The initial linear gradient of a plot of stress versus strain was taken as the Young's modulus (E).
This type of analysis informs on the nature of the event leading to clone formation as the gradient of the plot reflects the growth rate of the clones (Baker et al., 1978).
