Heterogeneous copy numbers of API2-MALT1 chimeric transcripts in mucosa-associated lymphoid tissue lymphoma.
Article in Leukemia, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
T(11;18)(q21;q21) results in a chimeric transcript between API2 at 11q21 and MALT1 at 18q21 and is a characteristic chromosomal aberration of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). API2-MALT1 chimeric transcripts are present in approximately one-third of all cases of MALT lymphoma. MALT lymphoma is also known to have variations in histological features and tumor cell proportions. Real-time polymerase chain reaction (PCR) was used to examine number of API2-MALT1 copies in clinical samples for further investigation of the pathophysiology of MALT lymphoma. A total of 13 samples of MALT lymphoma contained API2-MALT1 transcripts from 1.7 x 10(-2) to 1.0 copies/beta-actin copy. These findings were compared to the proportions of tumor cells in genomic VDJ PCR products determined by Southern blotting. Tumor cell ratios varied widely among the patients' samples, and no significant correlation was found between transcript copy number and tumor cell ratio. These results suggest that copy numbers of API2-MALT1 do not reflect tumor cell proportions, and that the number of copies of API2-MALT1 in a tumor cell is different for each clinical sample.
