Label amount per capsuleRange used in studiesReference level

Log scale: each gridline is ten times the one before. Studied ranges are daily amounts from the trials linked on each row; rows marked as a reference show a reference level, not a study dose. A bar being far away does not mean the capsule is unsafe or useless; it means the study results cannot be borrowed for it, because none tested SodaSlim or this five-row combination.
