The Association of Serum Carcinoembryonic Antigen, Carbohydrate Antigen 19-9, Thymidine Kinase, and Tissue Polypeptide Specific Antigen with Outcomes of Patients with Metastatic Colorectal Cancer Treated with Bevacizumab: a Retrospective Study.

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 aim of our retrospective study was to analyze the association of selected tumor markers (TMs) including serum carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9), thymidine kinase, and tissue polypeptide specific antigen with outcomes in patients with metastatic colorectal cancer (mCRC) treated with bevacizumab. There is an increasing body of evidence from retrospective/observational studies that some serum TMs may be predictive of effect of targeted therapies in mCRC. In our study, the cohort included 152 patients treated with bevacizumab-based therapy between years 2005 and 2014 at Department of Oncology and Radiotherapy, Medical School and Teaching Hospital Pilsen. Serum samples for measurement of TMs were collected within 1 month before the initiation of bevacizumab-based treatment. In multivariate Cox analysis that included serum tumor markers and clinical baseline parameters, the number of metastatic sites (hazard ratio [HR] = 2.00, p = 0.001) and CEA levels (HR = 2.80, p < 0.001) were significantly associated with progression-free survival, whereas CA 19-9 levels (HR = 2.25, p = 0.008) were the only studied parameter associated with overall survival. Quantification of serum CEA and CA 19-9 is simple and readily available, and their candidate prognostic importance in the setting of antiangiogenesis therapy deserves to be studied in prospective trials.
