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

A common mutation causing thalassemia in Mediterranean populations is an amber (UAG) nonsense mutation at the 39th codon of the human beta-globin gene, the beta-39 mutation. Studies of mRNA metabolism in erythroblasts from patients with beta-39 thalassemia and studies using heterologous transfection systems have suggested the possibility that this mutation not only affects protein synthesis but also alters mRNA metabolism. The effects of this mutation on several steps in the metabolism of mRNA have been investigated by transfection of the gene into permanent cell lines bearing a temperature-sensitive RNA polymerase II. Several RNA expression studies were performed, including analysis of transcription, mRNA stability, mRNA splicing accuracy, and mRNA polyadenylation. The results suggest that the defect in expression of the beta-39 mRNA occurs at a step prior to the accumulation of mRNA in the cytoplasm.
