P values determined by Mann Whitney U nonparametric test:
*Significan p<0.05
**High Significan p<0.01
***Very High Significan p<0.001
N/A – Too few cases
N= number of disease rankings related to the top 10 causes of death
Ranking:
5=Diagnosis is fully captured by the code/codes
4=Diagnosis is almost fully captured by the code/codes
3=Diagnosis is partially captured by the code/codes
2=Diagnosis is less than partially captured by the code/codes
1=Diagnosis is not captured by the code/codes
