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

PP2A holoenzymes account nearly 50% of Ser/Thr phosphatase activities in human cells, yet their roles in oncogenesis remain largely unexplored. A PP2A holoenzyme consists of a catalytic subunit, a scaffold subunit, and a regulatory subunit. We previously reported that PR55α, a PP2A regulatory subunit, supports the tumorigenic and metastatic potential of pancreatic cancer cells, and this is associated with its role in promoting YAP activation, which is essential for tumorigenesis and progression in most solid tumors, including pancreatic cancer. However, the direct role of PR55α in tumorigenesis has not yet been assessed. Using telomerase-immortalized human pancreatic ductal cells (HPNE), this research reveals a mechanism in which PR55α/PP2A cooperates with oncogenic KRAS
