Figure 5: Funnel plot results of the articles. As shown above, most of the articles lied on top of the funnel plot which indicates the influential articles have a high probability of publishing. However, articles with small sample size were at the bottom of the right side from symmetrical line, indicating subjective judgment presence of bias. Unfortunately, the meta-bias analysis shows as there was no bias (coefficient = 0.598 and P = 0.155).
