Significance of elevated levels of collagen type IV and hyaluronic acid in gastric juice and serum in gastric cancer and precancerous lesion.
Article in Digestive diseases and sciences, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
BACKGROUND AND
aimsCollagen type IV and hyaluronic acid (HA) are the major components of basement membrane and extracellular matrix, respectively. Cathepsin D is an aspartyl lysosomal protease involved in the degradation of the basement membrane and extracellular matrix. The aim of this study is to investigate the clinical significance of collagen type IV and hyaluronic acid in gastric juice and serum in diagnosis of gastric cancer and the degrading effect of cathepsin D on collagen type IV and HA.
methodsFifty gastric cancer patients were enrolled in our study compared with 41 patients with precancerous lesion and 30 control subjects. Collagen type IV and HA in gastric juice and serum were analyzed by radioimmunoassay. Expression of cathepsin D and collagen type IV in tissue were analyzed by immunohistochemical staining with monoclonal antibodies.
resultsThe contents of collagen type IV and HA in gastric juice and HA in serum were significantly higher in patients with gastric cancer than those in patients with precancerous lesion and control group (p < 0.05, p < 0.0001). Gastric cancer patients with lymph node metastasis had a higher level of collagen type IV and HA in gastric juice than those in patients without metastasis (p = 0.049, p = 0.043). The expression of cathepsin D had significantly increased in patients with gastric cancer compared to the control group (p < 0.0001). The continuous expression of collagen type IV in basement membrane in gastric cancer group was lower than that in the precancerous lesion group and control group (p < 0.0001).
conclusionsThe analysis of collagen type IV and HA in gastric juice and serum may provide a simple aid in diagnosing gastric cancer and evaluating whether metastasis is occurring or not.
