The phrase "a decrease in positivity to" is correct and usable in written English.
It can be used when discussing a reduction in positive feelings, attitudes, or responses towards something or someone.
Example: "The survey results indicated a decrease in positivity to the new policy among employees."
Alternatives: "a decline in positivity towards" or "a reduction in positive sentiment for".
Quantification of cell death also revealed a decrease in PI positivity, particularly at later time points, in the Fadd shRNA casp9−/− cells compared to the pLKO transduced casp9−/− cells (Fig. 7D and E ).
We conclude that when a decrease in test positivity occurs for a known disease, it may suggest that a new disease agent is emerging in the population.
Each single increase in the number of close contacts was associated with a decrease in TST positivity (OR 0.96; 95% CI 0.94-0.98).
In this retrospective survey, the LDP group had a decrease in margin positivity rate but the tumor size was smaller compared with the ODP group and LDP was more likely to be performed at academic/research institutions.
In fact, an increased HER2-positive tumour proportion was observed with increased age at menarche, which is associated with decreased risk, and a decrease in HER2-positivity was observed with increased age at menopause, which is associated with increased risk (Table 2).
We found a higher BDV CIC positivity in younger patients and a decrease in BDV CIC positivity with the increasing age of patients.
Late ERP effects characterized by an increase in the late positivity potential (LPP), or a decrease in the N400 component, in response to positive words may be attributed to the "default" positive mood during typical laboratory conditions and could also reflect the mood congruency effect (positivity offset; Herbert et al. 2006; Herbert et al. 2008; Kiefer et al. 2007).
This will ensure 88% power to detect a decrease in CT and NG repeat positivity rate from 30%to15%5%, and 78% power to detect a reduction from 20%to10%0%.
In patient 2, a positive csf cytology and immunophenotyping showing lymphatic blasts, a decrease in donor-chimerism, and positivity for BCR-ABL qPCR in csf could be found serologically while MRI scans showed a slight enhancement and an increase in contrast agent uptake.
We conclude that when an increase in negative test results occurs (or decrease in positivity) it suggests that a new disease agent may be emerging in the population.
