Error rate comparison: MRA Literature vs. ACT NOW CE study

	Error rate (%)	95% PI	p-value	I2
MRA Literature	6.57	0.54–18.5	< 0.0001	0.998
		95% CI
ACT NOW CE Study (All-Fields)	1.04	0.77–1.34	< 0.0001	0.889

Note. MRA = Medical Record Abstraction; PI = Prediction Interval; CI = Confidence Interval; I² = Higgins and Thompson’s I² statistic for measuring the degree of heterogeneity, where ≤ 25%, indicating low heterogeneity; 25 – 75% indicating moderate heterogeneity; and > 75%, indicating considerable heterogeneity [37].
