Proportion of dogs that were MRSP-negative in relation to time from inclusion sample. The proportion of dogs found to be MRSP-negative (y-axis) in relation to time in weeks from inclusion sample (x-axis). MRSP negativity was defined as the cultures from all sample sites being MRSP-negative on two consecutive sample occasions; however, two dogs with one negative sample occasion each are included. Out of a total of 31 dogs, 17 became MRSP-negative. The last positive sample occasion for each of the 14 dogs that remained positive when leaving the study are shown as censored observations.
