Results are compatible with the absence of modulation and incompatible with DAMA\/LIBRA signal at 90% C.L. Results confirm our goal of reaching a 3 sigma sensitivity in 3.5 more years of data-taking.<\/p>\n<p>Before unblinding the data, the whole analysis procedure was fixed (<a href=\"http:\/\/arxiv.org\/abs\/1812.01472\">http:\/\/arxiv.org\/abs\/1812.01472,<\/a> accepted for publication in Eur.
