Finally, the MTI instruments on average needed significantly less (9.95%) acceleration to produce one thousand counts per minute when comparing the acceleration responses in the group of MTI and CSA units across all settings and time points (Table 6).
When compared to the CSA units the MTI instruments, on average, needed significantly (p < 0.001) less acceleration in order to produce 1000 counts*min-1 To our knowledge, no other study has examined and compared the effect of calibration on inter-instrument reliability after applying unit-specific calibration factors to data obtained both in the laboratory and in the field.
Prior generations of the instrument have, on average, detection limits around 100 parts per million, but with a better vacuum the scientists were able to achieve a detection limit of five parts per million.
Not surprisingly, the novice tester was the slowest on both instruments, taking on average, five minutes per guideline (range 3 7 minutes) with the iCAHE instrument, and up to 20 minutes per guideline using the AGREE II instrument (average 18 minutes (15 20 minutes range)).
Scores pertaining to stigma as captured by the PROQOL instrument were lower, on average, than all other domains and notable for lack of significant association with any of the clinical factors considered.
The estimated prevalence was 16.4% with no instrument error and was, on average, overestimated by 0.5 percentage points based on observed variance of instrument error from the NCG-study.
As expected with the increased read lengths from the 454 GS XLR70 Titanium instrument, our contigs were on average larger (mean = 500 bp) than those assembled in previous studies that used earlier 454 technologies with shorter reads (e.g., 197 bp, [ 5]; 247 bp, [ 7]; 440 bp, [ 16]).
We also found that, on average, instruments in the NCG-study slightly underestimated both weight (mean: –0.14 kg) and height (mean: –0.07 cm) measurements.
LIF and a commercial chemiluminescence (CL) instrument simultaneous observations of NO2 show a good linearity (LIF = 1.02 CL + 0.6 (ppb), R2 = 0.98) but there is a bias of the commercial instrument of about 0.60 ppbv on average.
Using Brazilian data, we find that implementing an equal-opportunity policy across pupils of different socio-economic background, by using per-pupil spending as the instrument requires multiplying by 6.8 on average the current level of spending on the lowest achieving pupils.
