The BCL-2 promoter (-938C>A) polymorphism does not predict clinical outcome in chronic lymphocytic leukemia.
Article in Leukemia, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis 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
The (-938C>A) polymorphism in the promoter region of the BCL-2 gene was recently associated with inferior time to treatment and overall survival in B-cell chronic lymphocytic leukemia (CLL) patients displaying the -938A/A genotype and may thus serve as an unfavorable genetic marker in CLL. Furthermore, the -938A/A genotype was associated with increased expression of Bcl-2. To investigate this further, we analyzed the -938 genotypes of the BCL-2 gene in 268 CLL patients and correlated data with treatment status, overall survival and known prognostic factors, for example, Binet stage, immunoglobulin heavy-chain variable (IGHV) mutational status and CD38 expression. In contrast to the recent report, the current cohort of CLL patients showed no differences either in time to treatment or overall survival in relation to usage of a particular genotype. In addition, no correlation was evident between the (-938C>A) genotypes and IGHV mutational status, Binet stage or CD38. Furthermore, the polymorphism did not appear to affect the Bcl-2 expression at the RNA level. Taken together, our data do not support the use of the (-938C>A) BCL-2 polymorphism as a prognostic marker in CLL and argue against its postulated role in modulating Bcl-2 levels.
