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

backgroundStudies have shown that the health literacy of the German population is low. The aim of this article is to analyze current developments in health literacy on the basis of recent data.

methodsThe Health Literacy Survey Germany 2 (HLS-GER 2) is a representative quantitative survey of the German-speaking resident population of Germany aged 18 and above. It was carried out in December 2019 and January 2020 by paper- assisted personal oral interview (PAPI). Data on health literacy and socio - demographic characteristics were acquired with an internationally coordinated questionnaire. The instrument for measuring general health literacy consisted of 47 questions that reflect an individual's ability to access, understand, appraise, and apply health-related information. The associations between general health literacy and sociodemographic factors were analyzed using bivariate and multivariate statistical tests.

results58.8% of the participants had low health literacy, characterized by rating at least one-third of the questions as "difficult" or "very difficult." Many respondents stated that they had difficulties accessing (48.3%), understanding (47.7%), and applying (53.5%) information, and even more of them (74.7%) reported difficulties appraising information. The correlation coefficients reveal that health literacy is weakly associated with the following variables: age, sex, social status, literacy, level of education, financial deprivation, migration background, and the presence of one or more chronic diseases.

conclusionThe findings of the HLS-GER 2 highlight the need for action in pro - moting health literacy in the healthcare system. As the explanation of variance is low, there are presumably other important determinants of health literacy that were not taken into account. Further studies should be performed to investigate societal conditions of supplying health information, for example, or social and personal characteristics.
