The share is frozen cycles / (fresh + frozen cycles). It describes treatment composition, not a comparison of birth probabilities.
One percentage scale relative to 2014: 0% is the starting value, +100% is a doubling, −50% is a halving. Lines show the yearly path; on a short screen, bars show the change to 2024. Equal distances mean equal relative changes. For shares, this is relative change, not percentage points. Gaps are not filled; original values and units are below.

Does shifting transfers in time change cycles per patient?
