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

In the present study, we addressed the molecular mechanism of the downregulation of reversion-inducing-cysteine-rich protein with Kazal motifs (RECK), a critical tumor suppressor that can potently inhibit angiogenesis and metastasis, in non-small cell lung cancer and its clinical significance. The methylation status of the RECK gene promoter was studied by methylation-specific polymerase chain reaction. RECK mRNA and protein levels were investigated by reverse transcription-polymerase chain reaction and western blot analysis. Downregulation of RECK was observed in 60% of the 55 tumors analyzed. Using methylation-specific polymerase chain reaction analysis methylation of the RECK promoter was detected in 63.6% (35/55) of the tumor tissues. A strong correlation between downregulation and promoter methylation was found in these tumors (P = 0.000005). More importantly, downregulation of RECK significantly correlated with lymph node metastasis (P = 0.038). Mutation of codon 12 of the K-ras gene was detected in 25.5% (14/55) of lung tumor tissues. Statistical analysis indicated that K-ras mutation was linked with RECK promoter methylation (P = 0.047) and downregulation (P = 0.023). Promoter methylation was also detected in human lung cancer cell lines, and the DNA methyltransferase inhibitor 5'-azacytidine reversed the expression of RECK and reduced the invasive ability of these cell lines. Collectively, our results suggest that downregulation of the metastasis suppressor RECK is caused by promoter methylation in non-small cell lung cancer and is associated with K-ras mutation and lymph node metastasis.
