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

The prognosis for patients with advanced stages of Ewing family tumors (EFT) is very poor. EFT express high levels of phosphatidic acid specific membrane-associated phospholipase A1 beta (lipase I, LIPI). LIPI is a cancer/testis antigen and the high tumor specificity suggests that LIPI might be an attractive target for new diagnostic and/or therapeutic developments. By using reverse transcriptase-polymerase chain reaction (RT-PCR), we observed simultaneous presence of multiple LIPI transcript variants in EFT. We cloned and sequenced these transcript variants from EFT cell lines. Sequence analysis indicated that all transcript variants were derived by alternative splicing. Homology modeling of corresponding protein structures suggested that different transcript variants differ in their regulatory lid domains. In addition, expression of receptors for lysophosphatidic acid (LPA) was analyzed in a panel of EFT cell lines by RT-PCR. We observed that EFT cell lines expressed high levels of LPA receptors. Different LIPI transcript variants present in EFT might be involved in the pathogenesis of EFT by signaling via these LPA receptors.
