Increased ALK1 copy number and renal cell carcinoma-a case report.
Article in Virchows Archiv : an international journal of pathology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses 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
There have been recent reports of a rare variant of renal cell carcinoma associated with upregulation of the anaplastic lymphoma kinase gene (ALK) arising as a consequence of chromosomal translocations. The tumours were described as having a characteristic morphology. Here, we describe a case with similar morphology characterised by eosinophilic cells, abundant intracytoplasmic lumina and scattered large ganglion-like tumour cells. There was focal staining for ALK demonstrated by immunohistochemistry. However, rather than exhibiting a chromosomal translocation involving ALK, the use of FISH and a break-apart probe demonstrated that there was increased copy number of intact 2p23, the chromosomal region containing the ALK gene. Furthermore, the use of comparative genomic hybridisation showed increase of the whole of chromosome 2 along with chromosomes 6 and 17. There was no evidence of loss of 3p nor of trisomy of 7 associated with clear cell and papillary carcinoma, respectively. We suggest that this demonstrates a novel mechanism of upregulation of ALK activity by increased copy number occurring during the development of a renal carcinoma with the characteristic ALK-associated morphology.
