Several models for the inclusive production of protons at backward angles are reviewed. From the model amplitudes, predictions for the ($p$,$2p$) differential cross section in which one of the protons is emitted in the backward direction are calculated. It is found that the magnitudes and angle dependence of the predicted cross sections vary significantly from one model to the next.
