Active NRT showed no clear difference in 6‐Month abstinence compared with placebo ‐ rs2036527 ‐ non‐Hispanic black or African American (low certainty).
Active NRT may leads to higher 6‐Month abstinence compared with placebo ‐ DRD4 (exon 3 48 bp) ‐ non‐Hispanic white (low certainty).
Active NRT probably leads to higher 6‐Month abstinence compared with placebo ‐ NMR ‐ non‐Hispanic black and white (moderate certainty).
Active NRT probably leads to higher 6‐Month abstinence ‐ slow NMR compared with placebo ‐ NMR ‐ non‐Hispanic black and white (moderate certainty).
Active NRT showed no clear difference in 6‐Month abstinence ‐ normal NMR compared with placebo ‐ NMR ‐ non‐Hispanic black and white (low certainty).
Active NRT showed no clear difference in 6‐Month abstinence ‐ heterozygous compared with placebo ‐ DRD4 (exon 3 48 bp) ‐ non‐Hispanic white (low certainty).
It is very uncertain whether active NRT changes 6‐Month abstinence ‐ homozygous major compared with placebo ‐ rs2036527 ‐ non‐Hispanic black or African American (very low certainty).
It is very uncertain whether active NRT changes 6‐month abstinence ‐ homozygous major compared with placebo ‐ DRD4 (exon 3 48 bp) ‐ non‐Hispanic white (very low certainty).
It is very uncertain whether active NRT changes 6‐Month abstinence ‐ homozygous minor compared with placebo ‐ DRD4 (exon 3 48 bp) ‐ non‐Hispanic white (very low certainty).
Active NRT showed no clear difference in 6‐Month abstinence ‐ heterozygous or homozygous minor compared with placebo ‐ rs2036527 ‐ non‐Hispanic black or African American (moderate certainty).
