      abstract     = {Colorectal cancer (CRC) screening can effectively reduce
                      cancer-associated mortality. In Germany, individuals over
                      the age of 50 or 55 have access to CRC screening services.
                      However, utilization rates are persistently low, particular
                      in the male population. This observational study
                      investigates the effect of standard versus gender-specific
                      invitation letters on utilization of CRC screening
                      services. We analyzed utilization rates of individuals who
                      were insured by a large health insurance fund in Bavaria,
                      Germany. Persons who became eligible for CRC screening
                      received a standard (2013-2014) or a gender-specific
                      invitation letter (2015-2016). We compared utilization rates
                      within 6 months after receipt of the invitation letter using
                      billing codes of the health insurance fund. Invitation
                      letters were sent to 49 535 individuals, of which
                      $48.8 \%$ were gender-specific. The overall utilization
                      rate did not differ between recipients of the standard
                      versus gender-specific invitation letter $(11.6 \%$ vs
                      $11.1 \%;$ RR: 0.97 [0.92-1.02], p = 0.19). However,
                      uptake of screening colonoscopy was significantly higher
                      among recipients of gender-specific invitations $(2.9 \%$
                      vs $3.5 \%;$ RR: 1.21 [1.04-1.39], p = 0.01), whereas
                      utilization of fecal occult blood tests declined
                      $(10.4 \%$ vs $9.7 \%;$ RR: 0.93 [0.88-0.99],
                      p = 0.016). Gender-specific design of invitation
                      letters can modify the patients' preference for specific CRC
                      screening services and increase the acceptance of screening
                      colonoscopy.},
