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

Earlier we had reported a guanine to adenosine substitution at position 125 (G125A) in the BAX promoter, and its association with higher stage of the disease and failure to achieve complete response to treatment in chronic lymphocytic leukemia (CLL) patients. The aim of this study was to test the hypothesis that G125A leads to a reduction in the transcription of the BAX gene and that this is a direct cause of altered BAX mRNA and protein expression. In lymphocytes of CLL patients, BAX mRNA expression was determined by RNase protection assay and Bax protein was detected by immunoblotting. The presence of G125A in the BAX promoter was associated with lower BAX mRNA (P=0.004) and protein (P=0.024) levels. In transient expression assays using wild-type and mutant BAX promoter sequences linked to Luciferase as a reporter, the G125A polymorphism reduced expression of the BAX promoter by 2.6-fold. These studies suggest a mechanism for the biological effect of the G125A.
