Using the TGCS (for 17 countries), in most countries labour induction increased (groups\u20092a and 4a), whereas multiple pregnancies (group\u20098) decreased. In countries with decreasing overall CS rates, CS tended to decrease across all TGCS groups, whereas in countries with increasing rates, CS tended to increase in most groups. In countries with the greatest increase in CS rates (&gt;1%), the absolute contributions of groups\u20091 (nulliparous term cephalic singletons, spontaneous labour), 2a and 4a (induction of labour), 2b and 4b (prelabour CS) and 10 (preterm cephalic singletons) to the overall CS rate tended to increase.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The TGCS shows varying CS trends and rates among countries of Europe.
