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
Fas (CD95-APO-1), a member of tumor necrosis factor receptor super-family, exists in two forms, transmembrane and soluble (sFas). It had been suggested that circulating sFas levels and/or tissue FasL may reflect the severity of invasive breast ductal carcinoma. Few studies showed that neither DNA-index nor ploidy is an independent prognostic indicator, and there is no correlation with clinical outcome. The S-phase fraction (SPF) has been shown to be useful prognostic factor in both node-negative and node-positive tumors. The present work was done to find a correlation between sFas, tissue FasL, ploidy and SPF with prognostic factors and survival of breast ductal carcinoma patients. The present study included two groups; a patients group comprised 30 patients with breast ductal carcinoma and a control group that comprised 15 patients with benign breast swellings. Serum sFas was measured using commercially available ELISA kit and tissue FasL expression was studied using avidin-biotine immunohistochemical staining technique. Cell cycle studies were performed using flow cytometry. Serum sFas was significantly higher in breast ductal carcinoma group than in the benign breast swelling control group. A significant negative correlation between serum sFas and overall survival was found. Tissue FasL expression was directly correlated with distant metastasis and poor overall survival. A significant direct correlation was found between moderate and high SPF with worse pathologic parameters. Serum sFas level, tissue FasL immuno-expression and S-phase fraction are independent prognostic factors in breast ductal carcinoma cases.
