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.
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 evolutionarily conserved shelterin complex has been shown to play both positive and negative roles in telomerase regulation in mammals and fission yeast. Although shelterin prevents the checkpoint kinases ATM and ATR from fully activating DNA damage responses at telomeres in mammalian cells, those kinases also promote telomere maintenance. In fission yeast, cells lacking both Tel1 (ATM ortholog) and Rad3 (ATR ortholog) fail to recruit telomerase to telomeres and survive by circularizing chromosomes. However, the critical telomere substrate(s) of Tel1(ATM) and Rad3(ATR) was unknown. Here we show that phosphorylation of the shelterin subunit Ccq1 on Thr93, redundantly mediated by Tel1(ATM) and/or Rad3(ATR), is essential for telomerase association with telomeres. In addition, we show that the telomerase subunit Est1 interacts directly with the phosphorylated Thr93 of Ccq1 to ensure telomere maintenance. The shelterin subunits Taz1, Rap1 and Poz1 (previously established inhibitors of telomerase) were also found to negatively regulate Ccq1 phosphorylation. These findings establish Tel1(ATM)/Rad3(ATR)-dependent Ccq1 Thr93 phosphorylation as a critical regulator of telomere maintenance in fission yeast.
