Correction: A meta-analysis of P2X7 gene-762T/C polymorphism and pulmonary tuberculosis susceptibility.

There are errors in the legends for Figs. 3–6. The complete, correct figure legends for Figs. 3–6 are:

Fig 3

Forest plot and ORs with 95% CI of P2X7–762T/C polymorphism and pulmonary tuberculosis risk (CC vs. TT).

Fig 6

Forest plot and ORs with 95% CI of P2X7–762T/C polymorphism and pulmonary tuberculosis risk (CC vs. CT+TT).

There are errors in Tables 1 and 3. Please see the corrected Tables 1 and 3 here.
