These categories of treatment were enrolled in a ratio of 3:2.\r\n\r\nThe CERTAIN substudy includes 2,814 patients across 43 sites, with 117 rheumatologists. All 2814 patients have a “true baseline” before drug start at which time an array of biosamples was collected including DNA, RNA, plasma and serum. These samples were also collected at 3 and 6 months, along with physician and patient outcome measures q3months through 12 months.\r\n\r\nThe CERTAIN study biosamples are a unique and valuable resource for companies looking to study biomarkers, genomics, genetics and their relation with deep prospective clinical outcomes.","description_withheld":null,"homepage":"https://www.corevitas.com/certain-rheumatoid-arthritis-registry","introduced_date":null,"introduced_date_note":null,"introduced_by":null,"license":null,"modalities":[],"tasks":[{"name":"Predicting Drug-Induced Laboratory Test Effects","url":"/task/predicting-drug-induced-laboratory-test","datasets_with_task":"/datasets/task/predicting-drug-induced-laboratory-test"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["CORRONA CERTAIN"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-25T09:33:49+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
