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

Porcine epidemic diarrhea virus (PEDV) is a devastating enteric pathogen in neonatal piglets, causing outbreaks with high mortality. The lack of effective vaccines or treatments makes elucidating host-pathogen interactions essential for developing control strategies. In this study, we identify phosphoenolpyruvate carboxykinase 2 (PCK2) as a host restriction factor that targets the viral nucleocapsid (N) protein for degradation, thereby suppressing PEDV replication. This PCK2-mediated antiviral effect was reversed by autophagy inhibitors, indicating the involvement of a selective autophagic. Mechanistically, we found that PCK2, the N protein, the E3 ubiquitin ligase Traf6, and the cargo receptor Tollip form a functional complex. Depletion of either Traf6 or Tollip disrupted the autophagy pathway, restored N protein stability, and consequently rescued viral replication from PCK2 inhibition. This study unveils a novel antiviral mechanism in which PCK2 orchestrates the selective autophagic degradation of the PEDV N protein, highlighting the PCK2-Traf6-Tollip axis as a promising therapeutic direction.
