  Figure 1.. PRISMA flowchart outlining the various databases used and inclusion criteria applied. The flowchart also shows how many studies were included after each round of assessment. Abbreviations: ECG, electrocardiogram; H&P, history and physical examination; PRISMA, Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

  Figure 2.. Bar graph showing the results of ECG and H&P for each of the 8 categories of cardiac disease identified in our study population. Abbreviations: ECG, electrocardiogram; H&P, history and physical; SCD, sudden cardiac death.

• 

  Figure 3.. Forest plot showing the results of the association of H&P with cardiac disease. It shows the log odds ratio along with a 95% confidence interval for each of the individual studies included in the meta-analysis as well as an overall estimate based on the random-effects model. These were then back-transformed into odds ratios. Abbreviations: H&P, history and physical examination. RE, random effects.

• 

  Figure 4.. Forest plot showing the results of the association of electrocardiogram with cardiac disease. It shows the log odds ratio along with a 95% confidence interval for each of the individual studies included in the meta-analysis as well as an overall estimate based on the random-effects model. These were then back-transformed into odds ratios. Abbreviation: RE, random effects.

  Figure 5.. Bar graph showing the results of ECG and H&P for each of the 6 categories of conditions associated with SCD. Abbreviations: ECG, electrocardiogram; H&P, history and physical; SCD, sudden cardiac death.

• 

  Figure 6.. Forest plot showing the results of the association of H&P with conditions associated with sudden cardiac death. It shows the log odds ratio along with a 95% confidence interval for each of the individual studies included in the meta-analysis as well as an overall estimate based on the random-effects model. These were then back-transformed into odds ratios. Abbreviations: H&P, history and physical examination. RE, random effects.

  Figure 7.. Forest plot showing the results of the association of electrocardiogram with conditions associated with sudden cardiac death. It shows the log odds ratio along with a 95% confidence interval for each of the individual studies included in the meta-analysis as well as an overall estimate based on the random-effects model. These were then back-transformed into odds ratios. Abbreviation: RE, random effects.
