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

objectivesMeasurement tools of health-related quality of life (HRQL) that are specific for the underlying disorder are inevitably needed to assess HRQL changes following specific treatment strategies. The aim of the current study was to develop a questionnaire assessing HRQL in patients with unilateral diaphragmatic paresis.

methodsFirstly, topics of health impairments covering physical, psychological, social and functional aspects were predefined by a physician expert panel to ensure face validity. Secondly, all predefined topics were rated by a patient group with unilateral diaphragmatic paresis (untreated: n = 11; postoperative: n = 9) using a 5-point Likert scale ranging from 'not relevant at all' (-2) to 'absolutely relevant' (+2) to guarantee content validity. Thirdly, only relevant topics (0 to +2) were used for item development, while non-relevant items (<0) were not subject for item development.

resultsIn total, 20 patients rated a total of 43 topics covering a broad spectrum of health impairment. 21 were considered as relevant for item development. Items are answered on a 5-point Likert scale ranging from 'completely untrue' (-2) to 'always true' (+2). The Diaphragmatic Paralysis Questionnaire (DPQ) Summary Score ranges from 0 (worst HRQL) to 100 (best HRQL). Finally, the German DPQ was professionally translated and transculturally adapted into English, Italian, Dutch, French, Greek and Spanish, using translation/back-translation procedures.

conclusionsThe DPQ is the first diseases-specific HRQL measure developed for patients with diaphragmatic paresis. In addition, the DPQ is available in 7 languages free of charge for non-profit purposes. CLINICAL
