SE group labels indicate decreasing SE deprivation from 1 = most deprived to 5 = least deprived; SHE group labels indicate decreasing SHE deprivation from 1 = most deprived to 5 = least deprived. L = linear trend; NL = non-linear trend; n.s. = non-significant trend; ↑ = positive trend (increasing with deprivation); ↓ = negative trend (decreasing with deprivation).
