Correction

After publication of the original article [1] the authors noted that the following errors had occurred:

  1. 1.

    In the section ‘Optimising the risk score’, the word sensitivity was used instead of specificity.

This has been corrected in the sentence below:

Choosing a less stringent cutoff of 1.1 would result in sensitivity of 85.9% but lower the specificity to 59.3% (Fig. 1e).

  1. 2.

    In the ‘Discussion’ section, the incorrect value was used for weight loss. Instead of β 1.9, the correct value should be β 0.9. This figure is correct in Table 3 of the original article.

This has been corrected in the sentence below:

The optimal risk score included oral thrush (β 1.7), fever (β 1.6), lymphadenopathy (β 1.5), weight loss (β 0.9), self-reported gonorrhea (β 1.6), receptive CLAI (β 1.1), and more than five sexual partners (β 0.9) (all in the preceding six months) (risk score E).
