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

purposeThe aims of this study were to estimate the extent to which the content of the EORTC QLQ-C30 and EORTC QLQ-BR23 goes beyond functioning and include global feeling of well-being.

methodsRespectively, 21 and 13 healthcare professionals agreed to link the EORTC QLQ-C30 and EORTC QLQ-BR23 to the ICF. Mappers were asked to independently identify appropriate codes for the corresponding items of the EORTC QLQ-C30 and EORTC QLQ-BR23 following standardized linking rules and methodology. A Delphi technique was used in order to reach consensus. The threshold of agreement was 70 %. Rounds were stopped when the threshold was obtained or when it was clear that no consensus would be reached.

resultsA total of 25 items out of 30 were endorsed for the EORTC QLQ-C30: 8 items were endorsed at the 4-digit level, 15 items at the 3-digit level, and 2 items reach the consensus that the items were not cover within the ICF. Only 2 items out of 23 did not reach consensus in the EORTC QLQ-BR23. Of the 21 items endorsed, 3 items were endorsed at the 5-digit level, 10 items at the 4-digit level, and 8 at the 3-digit level.

conclusionThis study demonstrates that the content of the EORTC QLQ-C30 goes beyond functioning and includes global feeling of well-being and that the content of the EORTC QLQ-BR23 is related to functioning. Furthermore, linking items to the ICF framework could be an additional method to validate the content of health-related questionnaires.
