  We complement the analysis of the anomalous top-Higgs coupling effects on the
secondary lepton distributions in the associated production of the top-quark
pair and Higgs boson in proton-proton collisions at the LHC of the former work
by one of the present authors by taking into account the quark-antiquark
production mechanism. We also present simple arguments which explain why the
effects of the scalar and pseudoscalar anomalous couplings on the unpolarized
cross section of the process are completely insensitive to the sign of either
of them.
