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

purposeIn gastric carcinoma, high expression of PRL-3, a protein tyrosine phosphatase, is associated with lymph node metastasis. We studied the relationship between PRL-3 expression and peritoneal metastasis in gastric carcinoma.

methodsImmunohistochemical analysis using the anti-PRL-3 antibody was done in 639 patients with gastric carcinoma including 89 with peritoneal metastases. We then compared the clinicopathologic characteristics of the PRL-3-positive and PRL-3-negative carcinomas.

resultsPRL-3 was expressed in 70.4% of the primary gastric carcinomas overall; in 80.9% of the cancers with peritoneal metastasis and in 68.7% of those without peritoneal metastasis (P = 0.020). PRL-3 expression was higher in peritoneal metastasis than in the corresponding primary gastric cancers (P = 0.028). PRL-3 expression was correlated with tumor stage (coefficient = 0.343, P = 0.01) and cancer progression, including lymphatic invasion (coefficient = 0.325, P = 0.02), extent of lymph node metastasis (coefficient = 0.322, P = 0.01), and peritoneal metastasis (coefficient = 0.316, P = 0.03). Patients who were PRL-3-negative had a better survival rate than those who were PRL-3-positive at all stages (stage I: log-rank P = 0.046, Wilcoxon P = 0.048; stage II: log-rank P = 0.035, Wilcoxon P = 0.041; stage III: log-rank P = 0.027, Wilcoxon P = 0.033; stage IV: log-rank P = 0.032, Wilcoxon P = 0.030).

conclusionsPeritoneal metastasis appears to be correlated with PRL-3 expression, tumor stage, lymphatic invasion, and extent of lymph node metastasis. PRL-3 expression was negatively correlated with prognosis in patients with gastric cancer.
