Firstly, objective acceptance criteria are needed to compare the efficiency of the sample to that of the standard curve, in a manner similar to that already proposed for the comparison of standard curves [ 22].
For some in vitro bioassays, results are expressed in chemical equivalents, comparing the response induced by the sample to that induced by the reference chemical (positive control).
Comparing the starting sample to that at 40 h, the relative abundance of cellobionic acid in the media decreased (Fig. 1b).
The metabolite identity was determined by comparing the mass spectra similarity of the samples to that in the mass library with match level ≥ 75% and RI deviation ≤5.
Vicenin-2 was confirmed using HPLC analysis and UV/Vis spectroscopy by comparing the aqueous fraction sample to that of the standard Vicenin-2 compound.
48 The extent to which our findings can be generalised to the rest of the population of PLHIV at the Yaoundé Central hospital will be verified by using a large (predetermined) sample, comparing the sociodemographics of our sample to that of the parent population and by investigating any refusals to participate.
Comparing the infected samples to healthy cells, researchers found that the HIV infection was enhanced within cells that were dosed with cocaine over a period of three days.
The adherence was calculated by comparing the absorbance of the unknown samples to that of a standard curve.
However, when comparing expression levels in the LCM samples to that in the bulk samples, or when comparing expression levels in the linear-amplified bulk samples with that in the bulk samples, there were substantially more divergent probesets identified.
When the number of categories is reduced by excluding one type of fracture, this will change the prevalence of the different fracture types in the sample compared to that of the population at risk, and thus changing the kappa statistics.
Comparing your output to that of the sample solution is also a good way of debugging your program.
