1 · What the graph read from it

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.

2 · The registry

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

backgroundIGF-binding protein 3(IGFBP-3)has previously been identified as tumor marker. The present study aimed to investigate the clinical significance of serum IGFBP-3 in colorectal cancer (CRC).

methodsSerum was collected from 70 CRC patients and 50 healthy volunteer controls. Serum IGFBP-3 and carcinoembryonic antigen (CEA) levels were measured using electrogenerated chemiluminescence immunoassay and compared between groups. Relationships between serum IGFBP-3 level and the clinical characteristics of CRC were also analyzed. A receiver operator characteristic (ROC) curve was plotted to investigate diagnostic efficacy of serum IGFBP-3 and CEA, respectively, for CRC. Data were analyzed using SPSS 13.0.

resultsSerum IGFBP-3 levels in CRC were lower than those of controls (4.68 [3.56, 5.77] vs 5.44 [4.77, 6.10] µg/mL, P < 0.05). Furthermore, serum IGFBP-3 levels were higher in early cancer stages (I and II) than those of advanced stages (III and IV) (4.78 [3.92, 5.49] vs 3.77 [2.65, 4.59] µg/mL, P < 0.05). In addition, patients with lymph node metastasis absent had elevated serum IGFBP-3 levels than those of patients with lymph node metastasis present (4.73 [3.92, 5.72] vs 4.11 [2.45, 4.83] µg/mL, P = 0.02). Finally, ROC curve indicated that serum IGFBP-3 had a better diagnostic power for CRC than CEA. When serum IGFBP-3 and carcinoembryonic antigen were used together to detect CRC, the AUC was 0.949, with a sensitivity of 75% and a specificity of 90%.

conclusionsSerum IGFBP-3 might be a potential biomarker for CRC.
