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

Although TERT promoter mutations have been associated with a worsened prognosis in melanoma, the relationship between mutation status and downstream telomerase activity and telomere length remains convoluted. Using Sanger sequencing and techniques based on quantitative reverse transcriptase in real time, we evaluated 60 melanoma cell lines for TERT promoter mutational status, copy number, gene expression, and telomere length to provide a comprehensive analysis of the TERT/telomere pathway and establish a classification system whereby the associations between TERT mutations and their downstream molecular manifestations can more easily be ascertained. Mutations at positions -124/125 and -146 were associated with the highest levels of TERT gene expression but had no appreciable impact on absolute telomere length. In contrast, the common variant rs2853669 (at position -245) was significantly associated with longer telomere length via a recessive model in our cohort (P = 0.003). Our results, which are from assays performed on purified melanoma cell lines, suggest that the TERT promoter harbors a more complex mutational landscape than previously thought. Furthermore, the failure of TERT promoter mutations to consistently correlate with TERT expression and telomere length suggests an alternative method whereby tumor cells escape the critical shortening of telomeres.
