Wikipedia hosts not only basic factual information regarding the recent elections but excellent analysis as well, particularly regarding the relative efficacy this time of preference voting with  3 out of 13 getting positions thanks to preference voting: Zaborska (KDH), Mikolasik (KDH) and Paska (SNS–though helped perhaps by his famous Smer namesake?).   Full information is here.

Thanks to a reader for pointing it out and…I suspect…for providing the said analysis.
