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

Structural maintenance of chromosomes flexible hinge domain containing 1 (SMCHD1) has been shown to be involved in gene silencing and DNA damage. However, the exact mechanisms of how SMCHD1 participates in DNA damage remains largely unknown. Here we present evidence that SMCHD1 recruitment to DNA damage foci is regulated by 53BP1. Knocking out SMCHD1 led to aberrant γH2AX foci accumulation and compromised cell survival upon DNA damage, demonstrating the critical role of SMCHD1 in DNA damage repair. Following DNA damage induction, SMCHD1 depletion resulted in reduced 53BP1 foci and increased BRCA1 foci, as well as less efficient non-homologous end joining (NHEJ) and elevated levels of homologous recombination (HR). Taken together, these results suggest an important function of SMCHD1 in promoting NHEJ and repressing HR repair in response to DNA damage.
