Text: the analyses performed in this ms utilized two datasets, as described (stage i and stage ii). stage i data can be found here: dbgap study id phs000931.v1.p1 stage ii genotype and phenotype data cannot be provided to dbgap from five of the eight rcts. two rcts are from the 1990s and informed written consent was not obtained for individual level data sharing, and three rcts do not have permission from their institutional review board to share data other than the data already provided to dbgap and to the pharmacogenetics of nicotine addiction treatment consortium. therefore i will not submit individual level data from stage ii of this analysis to dbgap as the remaining data from stage ii (10 snps in three rcts) would be an incomplete dataset (representing 0% of the rct data with baseline nmr, and 32% of the rct data with baseline nicotine dependence and prospective abstinence measures). readers may contact andrew w bergen phd to request data from the three remaining rcts.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
