1 · What the graph read from it

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.

2 · The registry

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

backgroundSystemic sclerosis (SSc) is a multisystem disease with underlying immune mechanisms.

aimsTo investigate the clinicopathological characteristics of the lesions; immunological alterations in the bronchoalveolar lavage fluid (BALF), peripheral blood, and skin; and correlations between the clinicopathological characteristics and immunological alterations in SSc. MATERIALS/

methodsSkin biopsies, BALF, and peripheral blood samples were obtained from 19 patients (18 women, one man) with SSc and six age and sex matched healthy controls (HCs). Mononuclear inflammatory cells (MICs), CD4/CD8 cells, tumour necrosis factor alpha (TNFalpha), and interleukin 1beta (IL1-1beta) concentrations were examined in all samples using histological methods, enzyme linked immunosorbent assay, and immunoperoxidase staining.

resultsThe mean (SD) age of the patients with SSc was 34.8 (2.6) years. Proteinuria, positive rheumatoid factor, and C reactive protein were seen in 15.8%, 26.3%, and 26.3% of patients, respectively. Compared with HCs, there were significantly higher: total MICs (macrophages, lymphocytes), neutrophils, and eosinophils in BALF, blood, and skin (all p<0.05); cytokine concentrations in BALF (TNFalpha, p<0.001; IL-1, p<0.01) and peripheral blood (p<0.01 and p<0.05); and CD8/CD4+ T cells in peripheral blood (p<0.05). Compared with HCs, lesional skin had significantly higher histiocyte cell counts (p<0.05), lower lymphocyte counts (p<0.05), and higher CD4/CD8 ratios (p<0.001). There were significant correlations between cytokine concentrations and CD8+ T cells and forced vital capacity (p<0.001 and p<0.01, respectively).

conclusionsMICs, CD4/CD8+ cells, and cytokines are altered in SSc. These alterations correlated with the underlying disease process and therefore may have pathogenic, modulatory, and potential prognostic roles in SSc.
