Ancillary data collection

Concerning the frequency of sampling, in most cases, sampling could be done aimually. However, an important factor to consider in wildlife sampling would be season, as discussed in Section 5.2. Additional ancillary data to be collected on individuals, as previously noted, include whether live or dead specimen, age, sex, and site of collection on tissue. 

The following is a very simplistic example of what a time-to-event data set might look like when the event of interest is seizure. Here you assume that there is a seizure event form that collects whether a subject had a seizure and the date when the seizure occurred. You also assume that you do not need to search other ancillary data forms such as adverse events for seizure events. 

The statistical nature of the turbulent flame required the analysis of many temperature and density data points from separate pulses for accurate results. Thus, an overall computer system was used to control the various components of the combustion probe apparatus, and to collect and interpret the resultant data in an accurate and timely fashion. This system produced a block of data for each laser shot that included information about the Raman signals, LV readings, and ancillary data such as an identifying shot number and corresponding dye laser pulse energy. Typical current operation permits about twenty experimental run conditions daily, with up to several hundred shots per run. 

Automatix produces automated image analysis packages comprising data collection, spreadsheet analysis and charting to be used with the Macintosh computer. This has been used, in conjunction with ancillary equipment, to produce a computer digital analysis system [137] for around 4,000 [138]. Later, a more sophisticated system, costing around 20,000, was described for digital examination of film. 

These methods of measuring compliance continue to be used in clinical trials, although none of them fulhll the criterion of providing an accurate measurement of drug taken. Since they are not, in and of themselves, acceptable measures of compliance, they can only serve to confound the analysis and interpretation of the compliance exposure-response relationships. However, ancillary information from patient diaries, for example, may be helpful in interpreting data collected by other means—such as MEMS and others described above (24). A combination of MEMS and patient diaries may give an unbiased estimate of compliance. 

Certain relationships between the molecular parameters and chromatographic retention are very useful in qualitative studies. Prior to the development of GC/MS and other ancillary techniques, retention measurements were critically important in any identification efforts. This is well-documented by many laborious data collections in the earlier literature that are of little use in today s efforts. Whereas it is established that no serious structural elucidation can nowadays be based solely on solute retention studies, their utility in combination with various ancillary techniques should not be underestimated. 

All of the natural history collections described here may also be associated with ancillary collections of data in various forms, and derived specimens such as slide-mounted histological or dissected parts, SEM mounts, photographs, or frozen tissue. Table 6.7 is a basic list of the types of materials associated with each major group of animals. 

In the hydrolysis reaction for example, this ancillary information entails preliminary runs that establish T0 and Tx values over the temperature range to be traversed by the rampings. In adsorption studies, as a very different example, ancillary studies entail establishing the value of the monolayer. Yet again, in catalytic studies there is a need to calibrate sophisticated analytical procedures and to establish that the data will be collected in a diffusion-free regime. And in all cases there is the need to periodically calibrate flow meters, thermocouples, pressure sensors and so on. 

They can be useful for gathering ancillary information about a candidate. Although collecting some forms of ancillary information (such as personal, family, and social relationship data) is illegal, other (perfectly legitimate) information on such topics as work history and education that may have otherwise been unavailable can be collected in a well-structured interview protocol. 

Of course, almost every clinical trial, including most non-inferiority trials with efficacy primary endpoints, will collect and analyze safety data. The safety analyses done in an efficacy non-inferiority trial are essentially no different than those in an efficacy superiority trial. However, one possible distinction relates to the interpretation of the safety information in assessing the experimental treatment s relative benefits and harms. As stated previously, in some cases, improvement in safety might be an expected ancillary benefit of a treatment, and therefore, the lack of improvement might be seen as problematic. In addition, any unexpected harm caused by the experimental treatment might be less acceptable if the experimental treatment has simply demonstrated similar efficacy to a control than if it had demonstrated superior efficacy. 

For the initial studies of oral mucosa cells, normal cytological samples were harvested from laboratory volunteers, whereas clinical samples were collected at TMC, as described in Section 5.2.1.1, and immediately inserted into a vial filled with SurePath fixative. Data acquisition was carried out via the PapMap approach as discussed in Section 5.2.3.2 thus, for the first time, thousands of cellular spectra were available for statistical analysis. This large number of cells allowed several ancillary studies, for example, the immediate effects of smoking and over-the-counter medication on the spectra of oral cells, as well as the dependence of spectral characteristics on the site of cell collection. It was found that cells from the top of the tongue, the mouth floor, and the inside of the cheeks had slightly different spectral characteristics, which could be attributed to some different expression of proteins in these cells. Cells from the tongue, for example, had shghtly different...
