We analyze how corrections linear in the effective range, r_0, affectquantities in the three-body sector within an effective field theory forshort-range interactions. We demonstrate that observables can be obtainedstraightforwardly using a perturbative expansion in powers of r_0. Inparticular, we show that two linear-in-r_0 counterterms are needed forrenormalization at this order if scattering-length-dependent observables areconsidered. We exemplify the implications of this result using variousthree-body observables. Analytic results for the running of thenext-to-leading-order portion of the three-body force in this effective fieldtheory are provided. Expressions which incorporate O(r_0) corrections andrelate the positions of features observed in three-atom recombination near aFeshbach resonance are presented.
