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
backgroundTherapy adherence is a key factor in the control of type 2 diabetes mellitus (T2DM). Optimal self-care requires skills in health literacy (HL).
objectiveThis study aims to analyze the relationship between HL and adherence to therapy and to understand the possible influence of other sociodemographic and disease variables.
methodsA multicenter, cross-sectional study was conducted in Portuguese in 13 different primary health care units in both rural and urban environments. A sociodemographic questionnaire and two validated instruments, "Medical Term Recognition Test" and "Summary of Diabetes Self-Care Activities," were applied. The last value of hemoglobin A1c (HbA1c) and the number of chronic medications were collected from clinical records. Descriptive statistics and bivariate correlations were performed as well as multivariable linear regression to assess the association between HL and adherence to therapy. KEY
resultsParticipants (n = 354) were on average age 63.67 ± 10.39 years, 57.1% male and 42.9% female, 68.4% with inadequate HL and an average HbA1c of 7 ± 1.18%. Better HL was correlated with higher adherence to the total of self-care activities, nonpharmacological therapy, and foot care. In multivariable linear regression analyses, better HL (
conclusionIn a representative sample of people with T2DM in Portugal, HL was a key factor for greater adherence to demanding self-care activities. [
