The smallest statistically detectable mean difference between two dissolution runs was calculated (95% CI) to be 7% for one analyst, or 5% if two analysts were to perform the dissolution tests.
As seen in Figure 3, for a given desired power, the minimum detectable mean difference decreases as sample size increases.
At the end of sildenafil treatment, 17 digital ulcers were detectable (mean 1.1/patient), which was different from the number of ulcers at baseline (p<0.001, table 1).
On day 4, PAD1 mRNA expression was barely detectable (mean relative expression [RE] per cell, 0.6 ± 0.07, with respect to a common baseline standard), but thereafter progressively increased until day 6 (RE = 11.4 ± 0.69), after which no further increase during the first peak of parasitemia was observed.
The ELISA data from the plasma samples indicate that in control subjects, in most instances, TDP-43 was barely detectable (mean ± SD, OD = 0.02 ± 0.32), with just 8 individuals (8.8%) having absorbance (optical density or OD) values exceeding 0.11 (Fig. 2).
A six-state Markov model was constructed to estimate the sensitivity of mammography for invasive and in situ breast cancer and the screen-detectable mean sojourn time for non-progressive in situ, progressive in situ, and invasive breast cancer.
The screen-detectable mean sojourn time of preclinical non-progressive and progressive in situ cancers was 1.3 (0.4 to 3.4) and 0.11 (0.05 to 0.19) years, respectively, and 0.8 years (0.6 to 1.2) for preclinical invasive breast cancer.
Neither was oxygen detectable by means of an O2-microelectrode (lower detection limit, 1 µM; Revsbech, 1989) in cultures supplied with NO2− or NO.
Under these conditions we found that 44% of the constructs could be detected via half hairpin probes whereas 92% were detectable by means of barcode tiling probes.
The fact that DHT was detectable simply means that DHT levels were higher than E2 levels because the detection limits are rather similar between the two hormones.
In our study, organic layer and A-horizon served as complementary tracers for land-use legacies, since some of the effects of historical heathland farming were only detectable by means of properties of one of the humus horizons.
