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

purposeTo develop a psychometrically sound short version of the 13-item Lee Fatigue Scale using a Rasch model application.

methodsA convenience sample of 102 women with HIV/AIDS completed the Lee Fatigue Scale in the morning and evening. The scale was assessed using a Rasch analysis approach. We used a stepwise approach of removing the item with the least goodness-of-fit for internal scale validity in sequential analyses while monitoring unidimensionality and sensitivity to detect levels of fatigue.

resultsThe item reduction process terminated with a 5-item version (items 1, 4, 5, 11, and 12 from the original 13-item version). Analyses confirmed that both the original and short-form versions of the Lee Fatigue Scale demonstrated evidence of internal scale validity, unidimensionality, and sensitivity to at least three levels of fatigue (low, moderate, and high severity). Differential test functioning indicated that the original and short-form versions yielded similar ratings for 95 % of respondents.

conclusionA 5-item version of the Lee Fatigue Scale has satisfactory measurement properties and met criteria related to unidimensionality and ability to separate levels of fatigue. This version may be useful in studies measuring fatigue repeatedly over relatively short intervals.
