In this Endgames quiz (BMJ 2012;345:e5407, doi:10.1136/bmj.e5407) some subscript text was accidentally omitted in the third paragraph of the answers section. The first sentence should have read: “Spearman’s correlation coefficient in a sample is represented by rs, whereas in the population it is represented by ρs.”
