Which is the relevant table? I did not find “provider”
Ah, right, good question. My understanding is that provider variance is modeled as a random effect.[1] I was looking at Supplementary Table 5: iiuc, provider effects explain R2_conditional—R2_marginal ~ 50% of the variance, whereas fixed effects explain 17% of the variance.
Paragraph 2.2.1: “Data provider was treated as a random effect to account for potential differences in sampling and analysis methods, and the selection of sampling sites”

Thanks. That makes sense to me. Here is a brief explanation of fixed and random effects from Gemini.
