Yet, there is currently no validation of the best method to be used to measure FDG uptake in tumours and the cutoff thresholds of decline in uptake to consider for identifying responding tumours [ 6– 8].
Criterion A measures extinction risk based on exceeding a threshold of population decline (30% for Vulnerable, 50% for Endangered, and 80% for Critically Endangered) over a timeframe of three generation lengths, a measure of reproductive turnover rate, in the recent past.
There was, however, an increased incidence of adverse perinatal outcome associated with planned birth at home in nulliparous low risk women, resulting in the probability of it being the most cost effective option at a cost effectiveness threshold of £20 000 declining to 0.63.

In terms of absolute thresholds of CA19-9 decline, 68.4% of patients achieved at least a 25% decline in CA19-9; 52.6% of patients achieved at least a 50% marker decline; and 31.6% of patients achieved at least a 75% marker decline (Table 3).
Additionally, we carried out sequential analyses examining correlation between CA19-9 decline and patient outcomes, this time using various thresholds of percentage decline as cutoff points.
It appears that there is a threshold for the amount of decline possible in the number of sensitised effector cells (SFUs) per unit time with treatment, depending on the initial result.
As the gDNA hybridisation intensity threshold increased, the ratio of the control genes from the two pools of differentially-spiked samples increased to the expected value of 2 at a gDNA hybridisation threshold of 300, before declining again as the gDNA hybridisation intensity threshold was increased still further.
CN individuals who are Aβ-positive and have stable longitudinal memory performance may represent the group of asymptomatic AD or may not have reached a threshold of pathology where memory decline is evident.
Temporal ordering is a feature of cascade theories of ageing in which accumulation of deficits occur in a general sequence, potentially leading to an acceleration of decline once a threshold is reached.
