q2 · i? · associational · r2

Career-age composition analysis across four career stages (junior, early-career, mid-career, late-career) in both datasets, shown in Fig. 3. The article states teams employing AI-assisted writing "consistently comprise more junior authors and fewer senior authors", with a broad senior shift for PLoS but mainly a late-career reduction for Nature.

"Teams employing AI-assisted writing consistently comprise more junior authors and fewer senior authors."
