Interferon-γ (INF-γ) significantly reduced the proliferation of LTS-derived fibroblasts when compared with untreated fibroblasts on days 3 (mean difference, −6515; 95% CI, −10 630 to −2600), 4 (mean difference, −14 182; 95% CI, −22 860 to −5505), 5 (mean difference, −29 766; 95% CI, −47 550 to −11 981), and 6 (−47 521; 95% CI, −81 285 to −13 757) in all 6 patient samples. Error bars indicate 95% CIs.
aP ≤ .01 compared with untreated fibroblasts.
