Running Correlated Findings for
Nicardipine using default settings generates the report shown below.
The Report contains the following elements:
Fisher's transformation (Fisher, 1921
1, 1970
2) of the correlation coefficient is calculated for all pairs of tests by CDISC findings domain, with each site (the suspect site, indexed with
s) compared to all other sites taken together as a reference (indexed as
o). Corresponding
p-values are calculated according to a normal approximation.
FDR p-values are calculated and the reference line is determined as described in
How does JMP Clinical calculate the False Discovery Rate (FDR)?.
You can specify whether to search all results in original units when you Analyze: the data or restrict the search to either character results (in standard format) or numeric results (in standard units).
You can opt to Consider BY variables in the analysis. This option, which assumes that BY variables (left vs. right arm for collecting blood pressure data, for example) are included in the experimental design, is selected by default. You can uncheck this option to ignore BY variables.
Use the Only include BY variables if they are domain keys option to subset the available variables to only include those variables that are domain keys. If the option is unchecked, the report uses the cross-classification of
xxCAT,
xxSCAT,
xxLOC,
xxMETHOD,
xxPOS,
xxSPEC, and
xxTPT for creating by groups for all variables that are available (as it had in the past).
The Summarize sites with at least this many subjects: option enables you to set a minimal threshold for the sites to be analyzed. Only those sites which exceed the specified number of subjects are included. This feature is useful because it enables you to exclude smaller sites, where small differences due to random events are more likely to appear more significant than they truly are. In larger sites, observed differences from expected attendance due to random events are more likely to be significant because any deviations due to random events are less likely to be observed.
The Alpha option is used to specify the significance level by which to judge the validity of the correlations generated by this report. By definition,
alpha represents the probability that you will reject the null hypothesis when the null is, in fact, true. Alpha can be set to any number between 0 and 1, but is most typically set at 0.01, 0.05, or 0.10. The higher the alpha, the lower your confidence that the results you observe are correct.
The Subset of Visits to Analyze options enables you to restrict to a specific subset of visits your search tests with similar and questionable results.
