Abbreviated versions of the shortened assessment of health literacy for adult emergency department patients: Derivation and testing.
Article in Cogent public health, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We aimed to derive and test abbreviated versions of the Shortened Assessment of Health Literacy-Spanish and English (SAHL-S&E) that accurately identify English- or Spanish-speaking lower health literacy adult emergency department (ED) patients. Recursive partitioning of the SAHL-S&E was used to derive four abbreviated versions of the SAHL-S&E by mode of administration (self-administered or staff-administered) and language (English or Spanish). Test performance characteristics of the four abbreviated versions of the SAHL-S&E in distinguishing persons with lower health literacy from those with higher health literacy were assessed against the original full version of the SAHL-S&E. The test performance characteristics of the self-administered English abbreviated SAHL-S&E were: AUC 0.84 (0.79, 0.89), sensitivity 0.84 (0.76, 0.91), and specificity 0.68 (0.61, 0.75); and for the self-administered Spanish version were: AUC 0.88 (0.85, 0.92), sensitivity 0.88 (0.82, 0.93), and specificity 0.78 (0.73, 0.83). For the staff-administered English version, the performance characteristics were: AUC 0.94 (0.91, 0.96), sensitivity 0.98 (0.95, 1.00), and specificity 0.74 (0.69, 0.80), and for the staff-administered Spanish version were AUC 0.89 (0.85, 0.92), sensitivity 0.89 (0.84, 0.94), and specificity 0.80 (0.75, 0.85). Although the four abbreviated versions of the SAHL-S&E performed well they differed by content, length, language and how they are administered, which could add complexity in their routine administration in emergency medicine practice.
