@dipetkov No. I don't know why those differ. I think they may differ slightly because the summary output uses the unadjusted covariance matrix while emmeans uses the adjusted covariance estimates in the K-R method. You can check this by adding mode = "satt" to the emmeans call; then I think they'll agree.

The std. errors are also different between the summary output and the emmeans contrasts output. Is this due to the Tukey adjustment also?
