Hello, Please I have a question regarding the within subject coefficient of variation. Is it dose dependent? Can I take a coefficient of variation from a study done on a 500mg dosage and use it to calculate the number of subjects in a trial that will be done on a 1000mg dosage. Thank you in advance. |

Hi Imph, ❝ […] within subject coefficient of variation. Is it dose dependent? If you have linear PK, generally yes. Otherwise, not necessarily. ❝ Can I take a coefficient of variation from a study done on a 500mg dosage and use it to calculate the number of subjects in a trial that will be done on a 1000mg dosage. See above. — Dif-tor heh smusma 🖖🏼 Довге життя Україна! ![[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 |
