Authors would like to correct the errors in figure 4 legend.


Figure 4 legend,

“Forest plots of the incidence of herniation pit (HP) in symptomatic hips (s) and asymptomatic…” should be corrected as “Forest plots of the incidence of herniation pit (HP) in symptomatic hips (a) and asymptomatic…”.

The corrected Fig. 4 legend is given below:

Fig. 4
figure 4

Forest plots of the incidence of herniation pit (HP) in symptomatic hips (a) and asymptomatic hips (b) between the groups with and without femoroacetabular impingement (FAI). The mean incidence of HP in symptomatic hips was similar between the two groups (OR 1.00; 95% CI 0.40–2.51; P = 1.00). However, the incidence of HP in asymptomatic hips was higher in the group with FAI than the group without FAI (OR 1.59; 95% CI 1.42–1.77; P < 0.0001)
