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

backgroundCaveolin-1 (CAV-1), the main scaffold protein in caveolae, is frequently deregulated in human cancer. Of importance, this protein has been described to show tumor suppressor or oncogenic properties depending on the cell type and the stage of the disease. In fact, its role in colorectal cancer (CRC) remains to be fully clarified due to discrepancies in the literature.

methodsWe analyzed CAV-1 by western blot in a set of early-stage CRC patients with paired tumor tissue and normal colonic mucosa available. CAV-1 mRNA and expression levels of miR-124, 133 and 802 were quantified by real-time PCR.

resultsWe found CAV-1 strongly downregulated in 76.2% of tumor samples and associated with the subgroup of elderly patients (p = 0.027). We observed by real-time PCR a lack of correlation between CAV-1 mRNA and protein levels in some cases with CAV-1 downregulated by western blot, and miR-124 deregulation was identified as a potential contributing alteration to decrease CAV-1 protein expression.

conclusionCAV-1 is commonly downregulated in patients with primary CRC, which suggests its tumor suppressor role in early stages of this disease. Moreover, based on our findings, the previous discrepancies observed in different studies to date could be due to a complex posttranscriptional CAV-1 regulation.
