Text: Self-reported numeracy was a strong predictor of accuracy of responses (odds ratio [OR] = 2. 6, P = 0. 008), and the impact of high numeracy varied across graphical type, having a greater impact on line (OR = 5. 1 ; 95 % confidence interval [CI] = 1. 6-16 ; P = 0. 04) and pie charts (OR = 7. 1 ; 95 % CI = 2. 6-19 ; P = 0. 01), without an impact on pictographs (OR = 0. 4 ; 95 % CI = 0. 1-1. 7 ; P = 0. 17) or bar charts (OR = 0. 5 ; 95 % CI = 0. 1-1. 8 ; P = 0. 24).
