"Recent" data for hip dysplasia
OFA provides summary statistics for all data in their database from 1974-2013. They also provide the data for animals born from 2006-2013, for comparison. The difference between these "recent" data and the values for each breed for the entire period of 1974-2013 are graphed below. Note that the complete data also contains the recent data, so this is not a comparison between animals born since 2006 vs before 2006. Also, the sample sizes for the recent data will be smaller, and this might result in under- or over-estimation of the true value for a breed.
