Conclusion
The agreement between CV-risk predictions of Framingham score and WHO/ISH charts was not satisfactory in Sri Lankans. However, the two versions (standard and low information models) of the Framingham score were in good agreement. Similarly, the two versions of the WHO/ISH charts (standard and low information models) were also in good agreement.
Therefore, in the absence of a specific or validated risk model for South Asians, using the same risk model in serial risk calculations of individual patients would be the best.
