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

We show that the time required to transcribe human genes larger than 800 kb spans more than one complete cell cycle, while their transcription speed equals that of smaller genes. Independently of their expression status, we find the long genes to replicate late. Regions of concomitant transcription and replication in late S phase exhibit DNA break hot spots known as common fragile sites (CFSs). This CFS instability depends on the expression of the underlying long genes. We show that RNA:DNA hybrids (R-loops) form at sites of transcription/replication collisions and that RNase H1 functions to suppress CFS instability. In summary, our results show that, on the longest human genes, collisions of the transcription machinery with a replication fork are inevitable, creating R-loops and consequent CFS formation. Functional replication machinery needs to be involved in the resolution of conflicts between transcription and replication machineries to ensure genomic stability.
