  We point out that the QCD corrections to the gluon-fusion Higgs boson
production cross section at the LHC are very similar to the corrections to the
Higgs decay rate into two gluons. Consequently, the ratio of these two
quantities has a theoretical uncertainty smaller than the uncertainty in the
cross section alone by a factor of two. We note that since this ratio is the
theoretical input to analyses of Higgs coupling extractions at the LHC, the
reduced uncertainty should be used; in previous studies, the full cross section
uncertainty was employed.
