Macro Parameters | DSName=input SAS data set GroupVar=two or more level numeric or alphanumeric grouping variable. Observations with missing values on this variable are deleted. If not present, then statistics are given for all data. NumVars=list of numeric variables to be summarized with mean +/- SD or median (min-max). Shortcut listsOK. FreqVars=list of numeric or alpha variables to be summarized with frequencies and/or percents. Alpha variables are allowed. Shortcut lists OK. Mean=Y|N. If Y, then variables in NumVars are summarized with N, mean +/- SD. Default = Y. Median=Y|N. If Y, then variables in NumVars are summarized with median (min-max). Default = N. If both Mean and Median are Y, then there will be two lines of output per variable in NumVars. Total=R|C|N|RC. R generates a column of statistics across all levels of the grouping variable. C generates a row of totals for each variable in FreqVars. It has no effect on NumVars variables. RC generates both row and column totals. N suppresses both totals. Default = C. P=T|W|N|TW. T generates p-values for variables in NumVars based on a pooled variances t-statistic. W generates p-values based on a Wilcoxon rank-sum statistic. TW generates both types of p-values. N suppresses p-values. Default = W. Fisher=list of variables in FreqVars for which Fisher's exact test is to be used. KW=list of variables in FreqVars for which a Wilcoxon rank-sum (or Kruskal-Wallis) test is to be used. FreqCell=N|RP|CP|N(RP)|N(CP)|RP(N)|CP(N). Cell contents for categorical variables. N is frequency. RP is row percent. CP is column percent. Default is N(RP). Missing=Y|N. If Y, then frequencies for variables listed in FreqVars will include rows for missing values. Default is N. The missing values are not included in p-value calculations. This parameter has no effect on variables in NumVars. Print=Y|N. Default isY. Label=N|L|NL. Controls labeling for variables in FreqVars. N for name, L for variable label, NL for both. Variables in NumVars always show only the variable label (which is the variable name if there is no label). Default = L. Examples Label=N displays SEX, Label=L displays Subject gender, Label=NL displays SEX (Subject gender). Out=output SAS data set to be printed with the Table1Print macro. Out1way=output SAS data set to be created by the npar1way macro (2+ groups) or the univariate macro (1 group). If Print=Y, then the npar1way output or univariate output is also printed. If Print=N, then this data set can be printed with the npar1wayprint macro. |

Special Features Attached | UCSF_Table1 Macro_Print |

Special Features Text | Dsname = name of data set created by logistic macro Space = Y/N. If Y, then a space is inserted after each variable. Spaces are always inserted after each model (Default = Y) The table1 macro automatically calls the npar1way macro (2+ groups) or the univariate macro (1 group) for more detailed output. To suppress this output, select Print=N and create an output file with out=. Then use table1print to print this file. |
