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

Background: There is no consensus regarding the most reliable and valid measures of cognitive dysfunction in adolescents and adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The Wood Mental Fatigue Inventory (WMFI) is commonly used in adults while the Pediatric Quality of Life Multidimensional Fatigue Scale (PedsQL MFS) is commonly used in adolescents. This study examined whether the WMFI was valid in adolescents. Methods: Over a two-year period, participants in a cohort study completed four questionnaires: PedsQL, PedsQL MFS, Functional Disability Inventory (FDI), and WMFI. We examined the validity of the WMFI in 55 healthy adolescents and 55 with ME/CFS, determined how well the WMFI and PedsQL MFS cognitive fatigue subscale correlated with one another and with general quality of life surveys, and examined each questionnaire's responsiveness to change over time. Results: The PedsQL MFS cognitive fatigue subscale and the WMFI had a strong negative correlation for both healthy controls and ME/CFS patients at baseline with R Conclusion: The WMFI had a high correlation with the PedsQL MFS cognitive fatigue subscale
