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

backgroundThe Tilburg frailty indicator (TFI) is a self-report measurement instrument which integrates the physical, psychological and social domains to assess frailty in older adults. The aim of this study was the adaptation of the TFI to a German version and testing of the psychometric properties. MATERIAL AND

methodsThis study surveyed 210 individuals aged 64-91 years living at home. The mean age of participants was M = 75.3±5.7 years with 62 % females. The internal consistency was tested with Cronbach's alpha. The test-retest reliability was calculated after 20 weeks. The German TFI was validated using alternative measures for assessment of the quality of life, e.g. Eurohis-QoL-8 and short form health survey (SF-12), the patient health questionnaire (PHQ), the geriatric anxiety inventory short form (GAI-SF), the social support scale (F-Soz-U-K-14) and the resilience scale (RS-11).

resultsThe internal consistency was acceptable with a value for Cronbach's alpha of 0.67. The test-retest reliability was good after 5 months α = 0.87 (physical domain r = 0.85, psychological domain r = 0.75 and social domain r = 0.84). The inter-item correlations ranged between - 0.06 and 0.57. Correlations with alternative frailty measures showed good convergent and divergent validity.

conclusionThis study showed acceptable psychometric properties of the German adaptation of the TFI which was found to be age and frailty sensitive. The results of the validity of the TFI support the three domains integrated in the frailty score. Further application and testing of the German TFI in primary care and clinical settings are suggested to consolidate the findings.
