Statistical test for funnel-plot asymmetry used to detect small-study effects or publication bias.
Egger's test regresses standardised trial effect estimates against their precision to formally test for funnel-plot asymmetry. A statistically significant result suggests small-study effects or publication bias may be inflating the pooled estimate, though the test has limited statistical power when the number of included trials is small, as is common in exercise-physiology meta-analyses.
