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
The objective of the study is to investigate the expression of human β-defensin-1 (hBD-1) and human β-defensin-2 (hBD-2) in vocal cord polyps using tissue microarray. Tissue specimens from vocal cord polyps (N = 51), vocal cord nodules (N = 26), and healthy vocal cords (N = 8) were retrieved from the biobank of the Department of Pathology of Tianjin Tianhe Hospital between 2003 and 2006 and immunostained on tissue microarrays for the quantitative analysis of hBD-1 and hBD-2 expression. hBD-1 expression did not differ significantly between healthy vocal cords, vocal cord nodules, and vocal cord polyps (p = 0.904). In contrast, hBD-2 expression was significantly higher in vocal cord polyps compared to vocal cord nodules and healthy vocal cords (p < 0.001). The expression of hBD-2, but not hBD-1, is elevated in vocal cord polyp epithelium. This suggests that hBD-1 has a more constitutive role in host defense in the vocal cords, whereas hBD-2 expression may be a result of local inflammation or the presence of invading pathogens.
