Everything the Spanish National Activity Registry publishes about IVF-SPAIN (ALICANTE) between 2014 and 2023: 10 years with data. Each year carries its own attribution, because each year is a separate publication of the registry.
Volume first
Activity comes before results on purpose: a high percentage over few cycles does not mean what the same percentage over many cycles means. The registry publishes cycles as bands and that is how we show them, never reduced to a single figure; transfers are an exact count.

Results, year by year
Each band is the interval the registry published that year: the floor and the ceiling of the estimate, not a point. There is no line joining the years, and that is deliberate — joining the centres of successive intervals would assert a trend the data does not support.

Gaps in the series, and how to read them
The registry’s province-by-province census returns empty for 2009 and 2010, even though the individual profiles for those years do exist and have been recovered one by one. A centre missing from a given year means the registry publishes no profile for it that year — not that it closed.
The registry’s template changed schema in 2014 and again in 2015: up to 2013, cycles, implantation and transfers are published without separating fresh from frozen embryos, and insemination is published for a single age band (“under 40”). That is why some years carry fewer series than others: it is what the source published, not a missing figure.
And most important: a change from one year to the next is not, on its own, an improvement or a decline. The patient mix changes, selection criteria change and, at small volumes, chance changes too. Wide intervals are precisely the signal that the exact number cannot be trusted.
