VAR checked 4,293 actions - an average of 12 per match - in the 380-game La Liga season, intervening a total of 121 times (3.14 per game) and leading to 114 changed decisions.
This included the awarding of seven red cards that on-field officials missed, with 60 goals awarded by video technology.
The CTA also said player protests were down 17.3%, while simulation dropped by 68% following the introduction of VAR.
"Our officials have adapted very well to the changes, but so have the fans and media, too. It's like we've always played with VAR," said CTA president Carlos Velasco Carballo.
