One more question about cytokine tested in 2020 vs 2021, could you please confirm that 30 cytokines are overlapped between 2020 and 2021 dataset only, not 45 cytokines? There’re:
That’s right. The 2020 cohort has different feature counts and less overlap when compared to the 2021 and 2022 datasets.
2020 plasma_cytokine_concentration (Olink) data has 263 cytokines, while the 2021 and 2022 plasma_cytokine_concentration datasets each have 45 cytokines. The plasma_cytokine_concentration feature overlap between the three cohort is n=30.
2021 and 2022 plasma_cytokine_concentration features have a complete overlap (n=45).
