Combining results across studies to analyze T-wave inversion findings together.
Refers to a meta-analytic or systematic-review technique in which individual study data or effect estimates concerning T-wave inversion (a repolarization abnormality on ECG) are statistically combined to increase sample size and precision. T-wave inversion itself is a nonspecific ECG finding seen in both pathological contexts (e.g., cardiomyopathy, ischemia) and benign athletic adaptation, so pooled estimates of its prevalence or prognostic significance should be interpreted cautiously given known heterogeneity across populations (athletes vs. general, age, ethnicity) and ECG interpretation criteria. The phrase describes the research method, not a clinical sign itself.
