Fig. 2From: Wnt-induced secreted proteins-1 play an important role in paraquat-induced pulmonary fibrosisSerum WISP1 protein concentration in the PF and NPF groups. PF, pulmonary fibrosis; NPF, non-PF; WISP1p1, WISP1 protein concentration on the first poisoning day; WISP1p3, WISP1 protein concentration on the third poisoning day. **P < 0.01, compared with patients in the NPF groupBack to article page
