Why the study?
Although the polygenic risk score (PRS) is seen as advantageous for predicting complex disease risk, a systematic evaluation of its influence on outcomes and predictive value was needed.
Does the polygenic risk score (PRS) improve the prediction accuracy for the incidence risk of 32 complex diseases compared to traditional clinical risk tools?

Does the polygenic risk score (PRS) improve the prediction accuracy for the incidence risk of 32 complex diseases compared to traditional clinical risk tools?
Polygenic risk scores can enhance disease risk prediction accuracy, particularly for early-onset cases, serving as a valuable complement to traditional clinical risk tools.
