Difference in boxing between PTS and UD?

PTS means a result on points, where a UD statement would be inappropriate. For example,

• historic fights may not have the judge's scores available in record, and therefore it is unsure whether a UD is what occurred

• a number of regions had only one person deciding points in their history, and UD implies more than one person

• any other situation where a decision on points was made but where there is not enough information to say it was UD, MD or SD (unanimous, majority or split).
