Alternatives: "a rise in the total of" or "an uptick in the aggregate of".
It turns out that by allocating inefficiently, more payment can sometimes be redistributed, so that the net effect is an increase in the sum of the agents' utilities.
Progressive disease (PD) was defined as an increase in the sum of the products of the greatest bi-perpendicular diameters of all measurable lesions by at least 25% or the appearance of new lesions.
An increase in H2 ≥20 ppm (parts per million) compared to the lowest measured value, an increase in CH4 ≥12 ppm compared to the value measured before the intake of lactose, or an increase in the sum of H2 and CH4 ≥15 ppm was considered as a diagnostic test for LM, as was increase in s-glucose < 1.1 mmol/L from baseline.
Progressive disease was defined as any one of the following: an increase in the sum of the bidimensional products of all known disease by at least 25% by cross-sectional imaging, an increase in enhancement of a previously treated lesion by cross-sectional imaging, the appearance of a new lesion, or evidence of neovascularization by angiography at week 14.
Progressive disease (PD) was defined as the appearance of one or more new lesions or an increase in the sum of diameters of target lesions of at least a 20%, taking as reference the smallest sum on study; in addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).
OR was calculated for a 1-SD increase in the sum of skinfold thicknesses.
Progressive disease (PD): At least a 20% increase in the sum of the diameters of the target lesions, using the smallest sum in the study as a reference (including the baseline sum if that is the smallest in the study).
