  Color transparency predicts that, in $(e,e'p)$ reactions at large $Q^2$, the
final-state interaction becomes weaker than the reference value predicted from
the free-nucleon cross section. This reference value is usually evaluated in
the dilute-gas approximation to Glauber's multiple-scattering theory. We derive
the leading-order correction taking into account two-body correlations. Large
cancellations are found so that the overall correlation effect is small.
