Dear zizou,

❝ Yes, it is always true. A significant treatment effect at 10% significance level (i.e. p < 0.1) will show up in all studies where the confidence interval does not include unity.

you are correct
However, the reverse implication isn’t airtight. When a confidence interval does include unity, it does not automatically mean that the p‑value will exceed 0.1.
