Erratum to: Using text mining for study identification in systematic reviews: a systematic review of current approaches

Following publication of our article [1], it has come to our attention that two of the formulae in Table 1 were incorrect. The formulae for the measures of precision and burden have been corrected (Table 1). We are publishing this erratum to update these formulae to the following:

Precision = \( \frac{TP}{TP+FP} \)

Burden = \( \frac{t{p}^T+t{n}^T+f{p}^T+t{p}^U+f{p}^U}{N} \)
