Figure 4
Figure 4 Doi plot evaluating publication bias. The Doi plot shows marked asymmetry with a Luis Furuya-Kanamori index of +5.19, indicating major publication bias or small-study effects. Deviation of the curve from symmetry around the vertical axis suggests potential overrepresentation of smaller studies with stronger positive associations. LFK: Luis Furuya-Kanamori.
