Association of the 6-minute walking test ratio and difference with pulmonary function in patients with interstitial lung disease.
Article in Saudi medical journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
objectivesTo examine the associations between 6-minute walk test (6MWT) and lung functions, blood gas analysis findings, fractional exhaled nitric oxide (FeNO), and hospital stay in interstitial lung disease (ILD).
methodsThe present retrospective study included patients hospitalized in Beijing Hospital of Traditional Chinese Medicine, Capital Medical University between September 2018 and December 2019. The outcomes included the difference between the actual and predicted 6MWT values (6MWT difference) and the ratio of the actual to predicted 6MWT value (6MWT ratio).
resultsThis study included 137 patients. The predicted 6MWT value was 519±61 m and the actual 6MWT value was 449 (196.5,694)m. The 6MWT ratio was 84.7±177.6 and 6MWT difference was 73.9±95.1 m. Fractional exhaled nitric oxide (FeNO) (β= -2.157, standard error [SE]=0.836,
conclusionIn ILD, 6MWT difference and 6MWT ratio were associated with FeNO and DLCO. The 6MWT value was not associated with hospital stay. Therefore, the 6MWT might be a surrogate marker of pulmonary function in clinical ILD.
