May warrant caution applying the US NIH equation to Mexican patients; leaves open the need for population-specific validation.
Does the US NIH prognostic equation accurately predict survival in a Mexican population of patients with primary pulmonary hypertension?
The US NIH prognostic equation for primary pulmonary hypertension has high sensitivity but low specificity for predicting survival in a Mexican cohort, suggesting a need to adjust the limits for poor prognosis.
Sandoval et al. (1994) studied this question.
