Serum GROβ: a potential tumor-associated biomarker for colorectal cancer.

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
objectiveThis study aimed to confirm the potential of growth-related gene product β (GROβ) as a biomarker for colorectal cancer. We compared serum GROβ levels in patients with colorectal cancer, healthy individuals and individuals with non-tumor diseases.
methodsWe measured serum GROβ levels with enzyme-linked immunosorbent assay in patients with colorectal cancer (123 preoperative samples and 66 postoperative samples), 88 healthy controls and 125 individuals with other diseases. Serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) were measured in all samples with an immunoluminometric assay. Statistical analyses were performed to determine associations between serum GROβ levels and clinical parameters for colorectal cancer. A receiver operating characteristic (ROC) curve was analyzed for GROβ, CEA and CA19-9.
resultsThe serum GROβ levels were much higher in patients with colorectal cancer (median: 96.15 pg/ml) than those in healthy controls (median: 43.28 pg/ml, P < 0.01) and other disease controls (median: 57.30 pg/ml, P < 0.01). Serum GROβ levels in colorectal cancer were correlated positively with tumor-node-metastasis staging (P < 0.01) and the depth of infiltration (P < 0.05), but not with the histological grade, tumor embolus, lymph node metastasis, gross pathologic tumor type, or patient gender. The sensitivity and specificity of the assay for serum GROβ were 56.1% (69/123) and 95.31% (203/213), respectively. The area under the ROC curve constructed with GROβ (0.834) was larger than that constructed with CEA (0.739) or CA19-9 (0.676) for discriminating colorectal cancer from matched controls.
conclusionThese preliminary results suggested that the serum GROβ level could be a useful biomarker for colorectal cancer diagnoses.
