Mae’r data’n cael eu hystyried yn arbrofol ar hyn o bryd, a dylid cymryd gofal wrth eu hystyried tra bo ansawdd a chywirdeb y data yn gwella. Mae Llywodraeth Cymru yn parhau i weithio gyda byrddau iechyd i wella ansawdd data a’r dulliau a ddefnyddir i’w casglu.
The data is currently classed as experimental, and should be viewed with caution as the quality and accuracy of data improves. The Welsh Government continues to work with health boards to improve data capture and quality.
