CD4 and systemic sclerosis: Although the difference in CD4/CD8 T cell ratio between SSc‐ILD and controls in the SSc‐ILD lung dataset did not reach statistical significance, this study found a clear trend of increased CD4/CD8 T cell ratio in SSc‐ILD lungs (1.3071 [0.8524–2.5038] vs 1.2038 [0.8209–1.8122], p = 0.2461) (Figure 4D right figure).
