The BIOSTANET Biostatistics Network strongly and firmly condemns the Russian state’s attack and invasion of Ukraine. It is an unjustified and cruel act that constitutes a serious violation of international law and an attack on democracy and freedom. BIOSTATNET will collaborate and cooperate through its nodes in all scientific initiatives that can help to achieve the withdrawal of Russian troops from Ukraine, an end to the conflict, and peace. BIOSTATNET joins the pain of the Ukrainian people and conveys its solidarity to the academic institutions of Ukraine.
