1 · What the graph read from it

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.

2 · The registry

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

objectiveTo investigate the relationship between literacy and numeracy and their association with health task performance.

methodsOlder adults (n=304) completed commonly used measures of literacy and numeracy. Single factor literacy and numeracy scores were calculated and used to predict performance on an established set of health self-management tasks, including: (i) responding to spoken information; (ii) comprehension of print and (iii) multimedia information; and (iv) organizing and dosing medication. Total and sub-scale scores were calculated.

resultsLiteracy and numeracy measures were highly correlated (rs=0.68; ps<0.001). In multivariable models adjusted for age, gender, race, education, and comorbidity, lower literacy (β=0.44, p<0.001) and numeracy (β=0.44, p<0.001) were independently associated with worse overall task performance and all sub-scales (literacy range, β=0.23-0.45, ps<0.001; numeracy range, β=0.31-0.41, ps<0.001). Multivariable analyses with both constructs entered explained more variance in overall health task performance compared with separate literacy and numeracy models (8.2% and 10% respectively, ps<0.001).

conclusionLiteracy and numeracy were highly correlated, but independent predictors of health task performance. These skill sets are complementary and both are important for health self-management. PRACTICE IMPLICATIONS: Self-management interventions may be more effective if they consider both literacy and numeracy skills rather than focusing on one specific ability.
