In this article, the unit “cm” was incorrectly used instead of the correct unit “mm” in the Abstract, Review, and Conclusion sections. The corrected expressions are as follows. Before correction: 1. Abstract (p. 481) Thirteen research were combined to determine the proportion of MCA length and pooled proportion was 16.53 cm (15.33 to 17.72 cm); I2=98%; <italic>P</italic>-value<0.01. Nine studies were combined to determine proportion of MCA diameter and pooled proportion was 2.85 cm (2.52 to 3.17 cm); I2=100%; <italic>P</italic>-value<0.05. M1 segment mean length is more on left side as compared to right side. Mean length in males (16.57±1.40 cm) is more than females (15.9±1.32 cm). Mean diameter of M1 segment is similar on both sides. Mean diameter in males (3.20±0.09 cm) is higher than females (3.14±0.18 cm). 2. Review (p. 487) Early bifurcation is MCA branching at 0.5 cm or less from origin. (Fig. 5B) [20]. Jain [73] reported branching at 1.6 cm. According to Dimmick and Faulder [63], it occurred at 1 cm. 3. Review (p. 490) Pooled mean length was 16.53 cm (95% CI, 15.33–17.72) with Higgins and Thompson I2 value of 98%. Pooled mean diameter was 2.85 cm (95% CI, 2.52–3.17) I2value of 100%. 4. Conclusion (p. 493) Mean M1 segment length and diameter is 16.53 cm and 2.85 cm, respectively. After correction: 1. Abstract (p. 481) Thirteen research were combined to determine the proportion of MCA length and pooled proportion was 16.53 mm (15.33 to 17.72 mm); I2=98%; <italic>P</italic>-value<0.01. Nine studies were combined to determine proportion of MCA diameter and pooled proportion was 2.85 mm (2.52 to 3.17 mm); I2=100%; <italic>P</italic>-value<0.05. M1 segment mean length is more on left side as compared to right side. Mean length in males (16.57±1.40 mm) is more than females (15.9±1.32 mm). Mean diameter of M1 segment is similar on both sides. Mean diameter in males (3.20±0.09 mm) is higher than females (3.14±0.18 mm). 2. Review (p. 487) Early bifurcation is MCA branching at 5 mm or less from origin. (Fig. 5B) [20]. Jain [73] reported branching at 16 mm. According to Dimmick and Faulder [63], it occurred at 10 mm. 3. Review (p. 490) Pooled mean length was 16.53 mm (95% CI, 15.33–17.72) with Higgins and Thompson I2 value of 98%. Pooled mean diameter was 2.85 mm (95% CI, 2.52–3.17) I2 value of 100%. 4. Conclusion (p. 493) Mean M1 segment length and diameter is 16.53 mm and 2.85 mm, respectively. The authors apologize for any inconvenience this mistake may have caused. </sec> </body> </article>
