I have following table of values:
25 75
38 162
The odds ratio is 0.7037 and log(OR) is -0.3514. For a contingency table with values a, b, c, and d, the variance of log(OR) is given by
(1/a + 1/b + 1/c + 1/d)
How can I calculate the p.value of log(OR) from this data in R (whether it is significantly different from 0)?
