Dear all, we know for a good while that under certain conditions the Type I Error (TIE) might be inflated. However, seemingly European assessors were either not aware of it or ignored it. Last week I saw a deficiency letter (don’t ask for the country): … in case of a value of 30% < CVRR <45%, it is recommended to check the control of the patient's risk type I error at the level of 5%. If an alpha adjustment is necessary, it is recommended that a BE estimate for the new CI of the T/R ratio be submitted to meet the extended bounds. Kudos! Almost correct. The area of inflated TIEs may reach below 30% and only rarely (say, for a 4-period full replicate in 24 subjects) to 45%. — Dif-tor heh smusma 🖖 ![[image]](https://static.bebac.at/pics/Blue_and_yellow_ribbon_UA.png) Helmut Schütz ![[image]](https://static.bebac.at/img/CC by.png) The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |

That subjunction is correct but not part of the everyday linguistic toolbox of those who do not speak a lot of English. My guess is MHRA or the Irish Medicines Board or it comes from someone who spent a lot of time taking English language classes  — Pass or fail! ElMaestro |

Hi ElMastro, » » … it is recommended that a BE estimate for the new CI of the T/R ratio be submitted to meet the extended bounds. » That subjunction is correct but not part of the everyday linguistic toolbox of those who do not speak a lot of English. My guess is MHRA or the Irish Medicines Board or it comes from someone who spent a lot of time taking English language classes Not quite.  Just before the mentioned text it read: … no confirmation is provided that variability in the reference drug exists and is not caused by emissions; please provide confirmation in the form of an emissions estimate. We guessed that outliers were meant by “emissions”.— Dif-tor heh smusma 🖖 Helmut Schütz The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes |
