Seventeen of 31 sensitive subjects had a positive correlation between perceived and real field intensity, and 13 had a negative correlation (nonsensitive group, 22 and 27 of 57 subjects, respectively), which can be expected by chance (Table 3).
When selection on observables is set equal to selection on unobservables, the coefficient of external locus of control seems particularly sensitive to high levels of positive correlation (ρ = 0.55) and changes sign.
Trees growing on the peatland site are less climate sensitive, but display positive correlations between annual growth and temperature of October and December in the early 20th century, while in the late 20th century, significant negative correlations exist with January and February temperatures.
The results are sensitive to increasing the level of positive correlation between the error terms, but the coefficient of low self-esteem remains positive and significant when selection on observable is set equal to selection on unobservables.
We found increased levels of urinary IL8/CXCL8 in relapsed steroid resistant children when compared to steroid sensitive patients in remission, with a positive correlation with urinary protein levels [ 7].
Human studies showed that the patency of the dentinal tubules is an important characteristic of sensitive dentin [ 6], with a significantly positive correlation between the density of tubules and the pain responses induced from exposed cervical dentin surfaces [ 32].
Geochemical data collected using the Sensitive High Resolution Ion MicroProbe (SHRIMP) shows a positive correlation between concentrations of the elements U, Th and Pb (ranging from 20 60 ppm, 30 110 ppm, and 14 36 ppm, respectively) and Th/U ratio (1.13 – 1.8) with the deformation microstructure.
There was a demonstrable positive correlation where cell lines most sensitive to MIF depletion also had the greatest change in Akt activity and vice versa.
The positive correlation between capacity estimates (K) and brain activation levels in most load-sensitive regions in the occipital, temporal, parietal, and frontal cortices, reflecting increased activity as the number of stored faces increased, suggests that activity in both low-level perceptual and higher-level cognitive areas is modulated by the amount of facial information stored in STM.
We also observe a positive correlation between the skewness and inter-profile reproducibility (Additional file 2: Figure S7), suggesting more sensitive antibodies may produce more consistent profiles between the two technologies.
