Hi John,

❝ You guys are messing with me... If the T/R Ratio is <0.8 or >1.25, how can you generate a 90 CI that is within 80.00 – 125.00 since the 90% CI consists of (PE ± values)?

If we are dealing with unscaled ABE, ElMaestro’s answer (and your doubt) is correct: No way.

VSL’s post is ambiguous:

❝ Study is passed in CI but mean T/R ratio is not within the 0.80-1.25.

If the study was reference-scaled, the (implied) BE limits may be much wider (my answer).
Example in FDA’s flavor: CV_WR 60%, implied limits 60.96–164.04%, CI 97.00–162.00%; would pass (CI within limits), but fail due to the PE of 125.36 >125.00%.
