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

backgroundPatients with axial spondyloarthritis (axSpA) often experience chronic pain and inflammation, resulting in physical impairments, reduced mobility and decreased physical activity. The modified short questionnaire to assess health-enhancing physical activity (mSQUASH) was developed to assess daily physical activity in patients with axSpA.

objectiveTo translate, cross-culturally adapt and linguistically validate the original mSQUASH into German for patients with axSpA.

methodsThe original mSQUASH was translated from Dutch into German using a multistep process (Beaton method) with forward-backward translations into German by bilingual Dutch-German lay people and experts. Any remaining discrepancies were resolved by a scientific committee, resulting in a prefinal German version. Field testing with cognitive debriefing interviews with patients with axSpA from diverse backgrounds led to a final German version.

resultsMinor discrepancies, primarily related to formalities, semantic errors and syntax were found during translations. These were addressed, resulting in slight wording modifications. The prefinal German version was validated through cognitive debriefing by 10 patients with axSpA, confirming its linguistic validity and equivalence to the Dutch version.

conclusionOverall, this study confirmed the final German mSQUASH as a comprehensive measurement instrument for daily physical activity. It can now be used as a patient-reported outcome by German patients with axSpA. This can enable cross-linguistic comparisons and expanding its utility across language barriers.
