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
Introduction: Tumor neovascularization, an essential requirement for malignant disease progression and metastasis, depends on the dysregulation of pro-angiogenic and anti-angiogenic activities. This study aimed to investigate the utilization of circulatory angiopoietins (Ang-1 and Ang-2), vascular endothelial growth factor (VEGF-A and VEGF-C), and basic fibroblast growth factor (bFGF) as a prognostic tool for acute myeloid leukemia (AML). Material and methods: Twenty-four AML patients who were under chemotherapeutic intervention were included. Patients' relapse status, responsiveness to chemotherapy, and remission status were obtained from their medical profiles. For comparative purposes, fifteen healthy subjects were included. Serum levels of growth factors were measured. Results: As compared to control subjects, AML patients had significantly lower average levels of Ang-1 (170.8 ±12.7 versus 59.2 ±12.5 ng/ml) and VEGF-A (56.0 ±13.1 versus 98.6 ±11.9 ng/dl) that coincide with a higher average level of Ang-2 (18.5 ±4.1 ng/ml versus 7.5 ±0.8 ng/ml). Spearman's correlation analysis defined a significant association of sAng-1 and sAng-2 with patients' response to chemotherapy (ρ = 0.488) and remission status (ρ = 0.476), respectively. According to the receiver operating characteristic (ROC) curve, downregulation of Ang-1 has good predictivity for poor responsiveness to chemotherapy (AUC = 0.781, Conclusions: In the context of AML, dysregulated circulatory levels of Ang-1 and Ang-2 are suggested prognostic markers to provide useful predictivity of patients' adverse responsiveness to chemotherapy and remission status, respectively.
