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

backgroundThis study aimed to determine the psychometric properties of the 19-item Audit of Diabetes-Dependent Quality of Life (ADDQoL-19) in Chinese patients with type 2 diabetes mellitus (T2DM) in primary care setting.

methodsThe ADDQoL-19 and SF-12v2 were administered to 386 Chinese patients with T2DM in public primary outpatient clinic in Hong Kong. Internal consistency reliability was determined by Cronbach's alpha, whereas construct validity was assessed by the Spearman's correlations between the scores of the ADDQoL-19 and SF-12v2. Independent t tests were used in known-group comparisons to identify the differences in the ADDQoL-19 scores between respondents with different duration of diabetes, treatment modalities, body mass index and glycemic control.

resultsThe ADDQoL-19 had a moderate to weak correlation with SF-12v2 in convergent validity but with statistically significant results in known-group comparisons. Good internal consistency was generated with an acceptable value of 0.81, which was comparable to original English version. Construct validity was proven except the convergent validity is found to be weak with the generic SF-12v2, which was similar to the results in prior psychometric studies.

conclusionsDespite weak convergent validity, the ADDQoL-19 was found to have a satisfactory psychometric property, especially known-group comparisons and internal consistency reliability in the primary care setting.
