Correlation study between clinical phenotypes and autoantibodies in systemic sclerosis in Southwest China.
Observational study in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study investigates the characteristics of baseline data and the correlation between autoantibodies and clinical phenotypes in patients with systemic sclerosis (SSc) from Southwest China. A total of 346 patients diagnosed with SSc between 2021 and 2023 were included. Clinical data and laboratory data were collected to analyze the relationship between autoantibodies and clinical phenotypes. The prevalence of hypertension and osteoporosis in female patients with SSc was significantly higher than that in male patients. Anti-Scl-70 antibody was positively correlated with Raynaud phenomenon, facial or acral swelling and interstitial lung disease. Anti-Ro52 antibody is positively correlated with pulmonary hypertension. Anti-Scl-70, anti-U1-nrNP, anti-SSA, and anti-Ro52 were associated with overlap syndrome of SSc and systemic lupus erythematosus. Anti-SSA and anti-Ro52 are associated with overlap syndrome of SSc and Sjogren syndrome. Anti-Scl-70 was found to be statistically different in platelet count (PLT), C3, C4, albumin, and C-reactive protein, as was anti-U1-nRNP in hemoglobin, immunoglobulin G, C3, total triglyceride, high-density lipoprotein and low-density lipoprotein, as was anti-SSA in hemoglobin, immunoglobulin G and erythrocyte sedimentation rate, as was anti-ro52 in white blood cell count (WBC) and IgG, and anti-CENP B in PLT. Our study showed that autoantibodies anti-Scl-70 and anti-Ro52 in SSc patients were associated with the clinical phenotypes of Raynaud phenomenon, facial or acral swelling, interstitial lung disease and pulmonary hypertension.
