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

purposeThe Alcohol Quality of Life Scale (AQoLS) is accepted as a useful measure in assessing impact of alcohol use disorders (AUD) on health-related quality of life (HR-QoL) in Western cultures. We aimed to assess the psychometric properties of the Japanese version of the AQoLS (AQoLS-Japan).

methodsThis was a 3-month, observational cohort study in patients undergoing routine treatment for AUD in Japan. HR-QoL was assessed using the AQoLS-Japan (34 items, 7 dimensions). Scale psychometrics were analyzed using correlative techniques.

resultsData from 132 patients were analyzed. Inter-item and item-scale correlations for the AQoLS-Japan scale were moderate to strong. Confirmatory factor analysis results supported the AQoLS-Japan structure but there was evidence of interdependency among some items and factors. Cronbach's alpha coefficients for internal consistency ranged from 0.73 to 0.97, and intraclass correlation coefficients for scores between test (baseline) and retest (2 weeks) ranged from 0.65 to 0.82. Convergent and divergent validity and known-groups validity were supported. Evaluation of within-group change demonstrated that the AQoLS-Japan total and domains consistently demonstrated statistically significant improvement (p < 0.001 in all cases) in HR-QoL over time. Estimates for minimal clinically important difference on the AQoLS-Japan total score ranged from 13.2 to 18.2 for group-level change and from 2.4 to 15.7 for a group-level difference.

conclusionsThe AQoLS-Japan is a reliable and valid measure of HR-QoL that is able to demonstrate benefits associated with the routine treatment of AUD in Japan.
