Data are per cent or median (Q1, Q3). Group 1: framed as chance of having an event and treatment benefits in natural frequencies; group 2: framed as chance of not having an event and treatment benefits in natural frequencies; group 3: framed as chance of having an event and treatment benefits with number needed to treat; group 4: framed as chance of not having an event and treatment benefits with number needed to treat.
