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

Background: Pulmonary rehabilitation (PR) is recommended for patients with interstitial lung disease (ILD). The impact of PR on exercise capacity, symptom management and mortality risk in ILD is well established; however, there are limited studies reporting on the minimal important difference (MID) for shuttle walk tests (SWTs) in the ILD population. The aim of this study was to establish the MID for both the incremental and endurance shuttle walking tests (ISWT/ESWT) in the ILD population and to evaluate the association with survival. Participants: The study includes 207 participants with ILD (mean±sd age 71.1±9.5 years, forced vital capacity 2.32±0.79 L) who completed PR. Results: The baseline ISWT was 251.4±153.3 m and ESWT was 217.7±136.3 s. There were significant improvements for both the ISWT and ESWT following the PR programme (44.5±77.0 m (p<0.001) and 312.3±338.6 s (p<0.001)). MID was calculated through a combination of distribution (0.5×sd) and anchor-based techniques (global rating of change (GROC) and receiver operating characteristic (ROC) analysis). The distribution-based technique yielded an MID of 38.5 m for ISWT and 169.3 s for ESWT. ROC analyses yielded an MID of 35 m for ISWT and 200 s for ESWT; and the GROC yielded an MID of 58.5 m for ISWT and 209.0 s for ESWT. Survival analysis showed that improvements in exercise tolerance are associated with improved survival. Conclusion: Our data suggest an MID of 35.0-38.5 m for ISWT and 170-209 s for ESWT for patients with ILD. The size of improvements in SWT is associated with a survival advantage in ILD individuals who attend and complete PR.
