Annual average concentrations of PM2.5 (177 monitoring stations), NO2 (134 monitors), and benzene, ethylbenzene, and 1,3-butadiene (53 monitors) were calculated using data from unique NAPS monitoring sites that were operating during 2006 (see Figure 1).
The shortest road travel distances between homes and the health facility utilized by patients for INR monitoring were calculated using Google Maps (https://maps.google.co.za/maps?hl=en) and entered into the study database.
Spirometry for monitoring was calculated as the percent of cases in which testing was performed in those ≥7 years of age in the past 12 months.
32, 33 Using these estimates and the calculated production costs of DAA combination regimens, an overall care package for HCV diagnosis, treatment, and monitoring was calculated.
The CF for DustTrak monitors used in mobile monitoring was calculated as the geometric mean of the CFs of the corresponding size fraction for all the fixed-monitoring sites in that neighborhood on the measurement day.
The envelopes of the monitored signals were calculated by using the Hilbert transform.
The drug acquisition costs as well as the monitoring costs were calculated as described in the pre-progression state.
Person-level data on monitoring status were aggregated into strata defined by medical center (41 categories), age group (4 categories), gender, presence/absence of depression, and presence/absence of cardiovascular disease, and monitoring rates were calculated for all strata.
Select cardiovascular (CV) parameters were monitored continuously or were calculated at predetermined times.
Samples were analyzed using multiple reaction monitoring and concentrations were calculated from the ratios of native and labeled ions in the samples compared to a 10-point calibration curve incorporating the three analytes.
