Abstract
We incorporate recent calculations of one-loop corrections for the reduced Ioffe-time pseudo-distribution to extend the leading-logarithm analysis of lattice data obtained by Orginos et al. We observe that the one-loop corrections contain a large term reflecting the fact that effective distances involved in the most important diagrams are much smaller than the nominal distance . The large correction in this case may be absorbed into the evolution term, and the perturbative expansion used for extraction of parton densities at the scale is under control. The extracted parton distribution is rather close to global fits in the region, but deviates from them for .
