      abstract     = {A combination of searches for top squark pair production
                      using proton-proton collision data at a center-of-mass
                      energy of 13 TeV at the CERN LHC, corresponding to an
                      integrated luminosity of 137 fb$^{-1}$ collected by the CMS
                      experiment, is presented. Signatures with at least 2 jets
                      and large missing transverse momentum are categorized into
                      events with 0, 1, or 2 leptons. New results for regions of
                      parameter space where the kinematical properties of top
                      squark pair production and top quark pair production are
                      very similar are presented. Depending on the model, the
                      combined result excludes a top squark mass up to 1325 GeV
                      for a massless neutralino, and a neutralino mass up to 700
                      GeV for a top squark mass of 1150 GeV. Top squarks with
                      masses from 145 to 295 GeV, for neutralino masses from 0 to
                      100 GeV, with a mass difference between the top squark and
                      the neutralino in a window of 30 GeV around the mass of the
                      top quark, are excluded for the first time with CMS data.
                      The results of theses searches are also interpreted in an
                      alternative signal model of dark matter production via a
                      spin-0 mediator in association with a top quark pair. Upper
                      limits are set on the cross section for mediator particle
                      masses of up to 420 GeV.},
