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

The regenerative capacity of adult bone relies on the rapid activation and lineage engagement of skeletal stromal and progenitor cells (SSPCs). While signaling pathways that regulate these processes have been extensively studied, the epigenetic mechanisms that constrain progenitor activation and lineage permissiveness during adult bone repair remain poorly defined. Disruptor of telomeric silencing 1 like (Dot1L), the sole histone methyltransferase responsible for H3K79 methylation, is essential for skeletal development, yet its function in adult skeletal regeneration has not been established. Here, we identify Dot1L as a key epigenetic regulator that limits the early regenerative response to bone injury. Genetic reduction of Dot1L activity in the Prrx1
