Shift tables, laboratory data

A laboratory shift table is a tabular display that can show you how a population s laboratory data change, or shift, over time. Often you want to see what happens to the patients lab values after therapeutic intervention. Did certain lab parameters drop below or above normal range Are there laboratory tests that have become of clinical concern A shift table can provide this information at a glance. Although the example that follows is focused on laboratory data, a shift table can be used to show the movement of any categorical data over time. 

The following is a table specification for a laboratory normal range shift table. In order to create this table, you need to have a laboratory data set where the lab values have been flagged as normal, low, or high. The highlighted items in the table shell are parameters that change for the laboratory data in the study. 

Shift tables. Tables used to summarize and interpret laboratory (or similar) data showing, by treatment, the numbers of patients who have shifted from having normal to having abnormal values during the trial and so forth. 

An examination of some laboratory runs with diluted C150-1-02 catalyst can illustrate this problem. In one run with 304°C at inlet, 314 °C at exit, and 97,297 outlet dry gas space velocity, the following results were obtained after minor corrections for analytical errors. Of the CO present (out of an inlet 2.04 mole % ), 99.9885% disappeared in reaction while the C02 present (from an initial 1.96%) increased by over 30%. Equilibrium carbon oxides for both methanation reactions were essentially zero whereas the equilibrium CO based on the water-gas shift reaction at the exit composition was about one-third the actual CO exit of 0.03 mole %. From these data, activities for the various reactions may be estimated on the basis of various assumptions (see Table XIX for the effect of two different assumptions). 

There are significant differences between data for systems studied in more than one laboratory (Table 5) which may arise from the causes mentioned above, and from the relative lack of precision inherent in isomer shift measurements. 

The data for mixed metal zeolites as first prepared by Scherzer and Fort (18) shown in Tables I and XI are quite extensive. The reported isomer shifts and quadrupole splittings are for the iron atoms in the anionic state. Each of these unreduced samples show Mossbauer spectra that are in close agreement with literature values of the corresponding iron coordination complexes. Typical examples of unreduced and reduced samples are shown in Figures 3 and 4. We note here that preparations 16 through 22 are new and are developments of our laboratory and that 9 through 15 are preparations based on the work of Scherzer and Fort (18). Samples 16 and 17 show that this method can be extended to other zeolites like ZSM-5. If no transition metal cation is used in the synthesis, no Mossbauer spectrum for the corresponding anion is observed. Therefore, the nature of the cation is critical and complexation of the anion to a cation is necessary for anion inclusion. Certain transition metal cations (Ru + for instance) do not seem to bind the anion. 

In the general text, the reference standard used for measuring the chemical shift will be cited, but in the Tables all shifts will be corrected to those of diethyl ether-boron trifluoride. This, in our opinion, is not the best standard to use as the reference resonance signal, and in our laboratories we have used dimethyl ether-boron trifluoride for many years. However, the possible advantage of using diethyl ether-boron trifluoride is that it is commercially available and we have deeided to refer all data in the Tables to that of diethyl ether—boron trifluoride. 

However, the chemical isomer shift observed is different for each type of source matrix. This means that although the data from one particular laboratory may be self-consistent, intercomparison of data from different institutions may be difficult. Chemical isomer shifts for the more common matrices are given in Table 5.1.

There are several references where this information has been tabulated and reference to the original work may be found. Nuclear Spins and Moments by G. H. Fuller and V. W. Cohen, Nuclear Data Tables, 5,433 (1969) contains data for all the elements. A later compilation by S. Gerstenkorn, J. Physique, 34, 55 (1973) entitled Nuclear Properties Deduced from the Optical Spectra of the Atoms, Nuclear Moments and Isotope Shift of the Actinide and Rare Earth Series, lists the data through 1973. A report Table of Nuclear Moments by V. S. Shirley and C. M. Lederer, Lawrence Berkeley Laboratory, LBL-3450 (Dec. 1974) is a listing of all the elements. They have made corrections to the magnetic dipole moments based on a revised proton moment and have also corrected for diamagnetic shielding.
