It may be absolutely true that a certain person may need so many milligrams of a certain medication, but another person may need more or less of the same medication to produce the desired effect.
Maaaring ganap na totoo na kailangan ng isang tao ang maraming miligramo ng isang gamot, ngunit ang ibang tao ay maaaring kailangan ng mas marami o mas kaunting miligramo ng parehong gamot upang magkaroon ng parehong ninanais na epekto.
