Key Takeaway
Note that TCM-WM models show high AUC but are limited by high heterogeneity and risk of bias.

This meta-analysis evaluated the diagnostic accuracy of TCM-WM integrated risk prediction models for coronary heart disease based on 16 included studies. The primary outcomes reported a pooled sensitivity of 0.79 (95% CI: 0.62 to 0.89) and a pooled specificity of 0.87 (95% CI: 0.76 to 0.94). The summary AUC was 0.90 (95% CI: 0.88 to 0.93), with a pooled odds ratio of 1.80 (95% CI: 1.40 to 2.30).

The authors noted several significant limitations, including a high or unclear risk of bias in 12 of the 16 studies. Furthermore, there was extreme between-study heterogeneity, specifically for specificity and odds ratios where I2 was greater than 95%. External validation was limited, as only 5 studies provided such data, and subgroup analyses were exploratory in nature.

Due to these methodological limitations and the high degree of heterogeneity, the findings are considered hypothesis-generating. The results do not establish reliable performance or clinical benefit across different clinical settings. The evidence is of low certainty for clinical decision-making.

Researchers looked at 16 different studies to see how well integrated risk prediction models work for coronary heart disease. These models combine Traditional Chinese Medicine (TCM) and Western Medicine (WM) to help identify patients at risk. The analysis found that these combined models showed a high area under the curve (AUC) of 0.90, with a sensitivity of 0.79 and a specificity of 0.87.

While the results look promising, there are important reasons to be cautious. The researchers noted that many of the studies had a high risk of bias and showed a lot of variation between each other. Only a small number of the studies were used to check the results in different settings. Because of these issues, the findings are currently considered exploratory.

Patients and doctors should view these results as a starting point for research rather than a confirmed tool for daily use. The study did not provide enough evidence to say these models will work reliably in every clinic. You should always talk to your doctor about the best way to manage heart health risks.

What this means for you:
Integrated models show promise for heart disease prediction but need more testing to be reliable for clinical use.

Common questions

How accurate are these integrated prediction models?

The study found that the integrated models had a summary AUC of 0.90, with a sensitivity of 0.79 and a specificity of 0.87. These numbers suggest the models have some ability to identify coronary heart disease, but the results are currently considered exploratory and not yet proven for routine clinical use.

Are these models reliable for every patient?

Not necessarily. The study noted significant differences between the studies included and a high risk of bias in 12 of the 16 studies. Because of this, the findings do not yet establish reliable performance or clinical benefit across different settings. You should consult a healthcare professional for personalized care.

What is the difference between these models and standard care?

These models combine Traditional Chinese Medicine and Western Medicine to predict risk for coronary heart disease. While the data shows a pooled odds ratio of 1.80, the high variability between studies means they are not yet a replacement for standard clinical practices.

BackgroundCoronary heart disease (CHD) remains a leading global cause of mortality, necessitating improved early risk prediction. Traditional Chinese Medicine (TCM) may provide complementary diagnostic information for models based on Western medicine (WM), but the performance and certainty of TCM-WM integrated models remain unclear.MethodsThis systematic review and meta-analysis evaluated TCM-WM integrated risk prediction models for CHD. Sixteen studies were included; diagnostic-accuracy outcomes were synthesized from 12 studies and odds ratios (ORs) from 7 studies. Heterogeneity, risk of bias, subgroup effects, and meta-regression findings were assessed.ResultsThe pooled sensitivity was 0.79 (95% CI: 0.62–0.89; I² = 98.17%), specificity was 0.87 (95% CI: 0.76–0.94; I² = 99.39%), and summary AUC was 0.90 (95% CI: 0.88–0.93). The pooled OR was 1.80 (95% CI: 1.40–2.30; I² = 95.6%). Twelve of 16 studies had high or unclear overall risk of bias, and only 5 studies reported external validation. Although subgroup analyses suggested possible differences according to the number of TCM predictors, these analyses were exploratory and did not resolve the extreme between-study heterogeneity.ConclusionsTCM-WM integrated models yielded favorable average discrimination estimates, but extreme heterogeneity, methodological limitations, and limited external validation substantially reduce certainty in the pooled estimates. The findings should therefore be considered hypothesis-generating and do not establish reliable performance or clinical benefit across settings. Multicenter prospective validation, standardized TCM definitions, and transparent reporting according to TRIPOD and PROBAST are required before clinical implementation.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420250652605, CRD420250652605.
