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
backgroundHealth-related quality of life (HRQoL) reflects an individual's own perception of their symptom burden, functional limitations, prognosis, overall health and changes associated with treatment. The HeartQoL is a validated heart disease-specific questionnaire with a physical and an emotional subscale that is used internationally to assess HRQoL in patients with coronary heart disease (CHD). The aim of this study was to translate and evaluate the psychometric properties of the HeartQoL in patients with CHD in Iceland.
methodsPatients ≥ 18 years (n = 396; mean age 64.4 ± 8.8 years; 79.6% male) admitted with CHD were recruited from two hospitals in Iceland and completed the Icelandic versions of the HeartQoL, Short-Form 12v2 Health Survey (SF-12v2), and Hospital Anxiety and Depression Scale (HADS). A subsample of 47 patients completed the HeartQoL 14 days later. Confirmatory factor analysis for ordinal data was used to evaluate the measurement model with a physical and an emotional subscale. Convergent and divergent validity, internal consistency, and test-retest reliability were evaluated.
resultsOverall, the hypothesized two-factor structure of the Icelandic version of the HeartQoL was supported. However, problems with cross-loadings and correlated error variances were identified. Convergent and divergent validity were supported in correlational analyses between HeartQoL, SF-12v2, and HADS. Internal consistency reliability, measured by ordinal alpha, was good for the physical (α = 0.96) and emotional (α = 0.90) subscale. According to intraclass correlations (ICC), acceptable test-retest reliability was demonstrated (ICC = 0.79-0.86).
conclusionWith the two-factor structure confirmed, the Icelandic HeartQoL demonstrated satisfactory psychometric properties in the sample of patients with CHD. Users of the instrument can use the original scoring.
