Measuring fatigue in cancer patients: a common metric for six fatigue instruments.
Article in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
purposeFatigue is one of the most disabling symptoms in cancer patients. Many instruments exist to measure fatigue. This variety impedes the comparison of data across studies or to the general population. We aimed to estimate a common metric based on six different fatigue instruments (EORTC QLQ-C30 subscale fatigue, EORTC QLQ-FA12, MFI subscale General Fatigue, BFI, Fatigue Scale, and Fatigue Diagnostic Interview Guide) to convert the patients' scores from one of the instruments to another. Additionally, we linked the common metric to the general population.
methodsFor n = 1225 cancer patients, the common metric was estimated using the Item Response Theory framework. The linking between the common metric of the patients and the general population was estimated using linear regression.
resultsThe common metric was based on a model with acceptable fit (CFI = 0.94, SRMR = 0.06). Based on the standard error of measurement the reliability coefficients of the questionnaires ranged from 0.80 to 0.95. The common metric of the six questionnaires, also linked to the general population, is reported graphically and in supplementary crosswalk tables.
conclusionsOur study enables researchers and clinicians to directly compare results across studies using different fatigue questionnaires and to assess the degree of fatigue with respect to the general population.
