I am reading a study which explains it has an odds ratio-1.95 and (95% confidence interval 1.47-2.59 p-<0.001) can anyone explain what this means please

Answer 1

1.95 odds ratio means odds are 1.95:1 for a certain condition to be true (usually outcome of treatment relative to baseline)

95% CI 1.47 to 2.59 means there is a 95% probability the plausible values for the true population parameters are between 1.47 to 2.59.

p < 0.001 could be in reference to the p-value, the probability of obtaining a sample statistic as the one computed.
