The value that is labeled "Zelen's Exact Test (P)" is the test statistic, and the value that is labeled "Exact Pr <=P" is the p-value for the test.
From the documentation (section "Zelen's Exact Test for Equal Odds Ratios"):
"The test statistic [for Zelen's test] is the probability of the observed table conditional on the fixed margins, which is a product of hypergeometric probabilities.
The p-value for Zelen’s test is the sum of all table probabilities that are less than or equal to the observed table probability, where the sum is computed over all tables in the reference set determined by the fixed margins and the observed sum of cell (1,1) frequencies. This test is similar to Fisher’s exact test for two-way tables.
For more information, see Zelen (1971); Hirji (2006); Agresti (1992)."
