Matched pairs analysis was used to examine the differences in the observed results for each indicator obtained using multiple data sources.
The indicators were obtained using the concept of ecological integrity, that characterize the landscape based upon manifest and latent variables of naturalness, stability and self-organization, according with the measures of spatial distribution of species and natural habitat.
To correct older pH measurements obtained using unpurified indicator: Use the archived unpurified indicator and purified indicator to make paired pH measurements in seawater over a range of pH values (e.g., 7.2 8.2).
The probability of concentrations of EC, SAR, Na+ and Cl− exceeding a threshold limit in groundwater was obtained using indicator kriging (IK).
This work demonstrates that a measure of photocatalyst activity of self-cleaning glass, i.e. the time taken to change the colour of an Rz photocatalyst indicator ink, can be obtained using inexpensive digital photography, as alternative to more expensive lab-based techniques, such as UV vis spectrophotometry.
Furthermore, regarding the pooled estimates, the combination of results obtained using different exposure indicators increases heterogeneity and the risk of bias in the meta-analytic estimates, in particular when thresholds or exposure-response curves are combined.
We explored the use of variant frequency as a quantitative predictor, but found that the best performance was obtained using a binary indicator of whether the variant has been recorded in a control database.
Nonetheless, the conclusions of analyses performed in this work (see Figures 2, 3, 4, and 5), obtained using the π indicator, do not change subtantially if we use the dN/dS ratio instead (data not shown).
We previously validated the accuracy of EVLW measurements obtained using the single-indicator technique in the postmortem lung samples and defined the statistically normal EVLW values in a human autopsy study [ 25].
