We followed STARD guidelines in our study's design and execution, although this was not declared explicitly. Health literacy and numeracy levels were computed after the ED visit. The proportion of minority patients reflects the racial distribution of our local geographic area. Education level and literacy levels vary by population and geography. Thus, optimal thresholds for identifying limited health literacy may vary according to study goals and prevalence of low health literacy, as positive and negative predictive values fluctuate. There was 4.5% inadequate and 7.5% marginal health literacy in Chew's original validation study. 4We used S-TOFHLA> 22 (adequate health literacy) as the comparison (alloy) standard. Carpenter's work focused on the test characteristics for identifying limited health literacy (inadequate or marginal health literacy, ie, S-TOFHLA< 22). To illustrate the impact definition of the reference standard has on interpretation of test characteristics, the area under the curve for the receiver operating characteristics (AUROC) for S-TOFHLA< 23 (ie, inadequate and marginal health literacy) was 0.26 in our study, versus AUROC of 0.74 for S-TOFHLA> 22 (ie, adequate health literacy).(Detailed tables of these analyses including measures of sensitivity and specificity are available online or by emailing candace. mcnaughton@ vanderbilt. edu). Similarly, when we compared our measure of subjective numeracy against less than average numeracy measured by the WRAT4, the AUROC was 0.23; the AUROC was 0.77 for identifying adequate numeracy.
