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 radioaerosol mucociliary clearance (PRMC) is a reliable method for assessing Material and methods: The study was based on a retrospective analysis of PRMC tests performed over a 24-year period (1999-2022) in individuals referred for PCD work-up and included patients with genetically confirmed PCD and non-PCD controls. Patients inhaled nebulised technetium-albumin-colloid before static and dynamic imaging was obtained. Three parameters were evaluated: 1-h lung retention (LR1), tracheobronchial velocity (TBV) and cough clearance. Results: The study included 69 patients from the Danish PCD cohort, representing 26 different PCD genotypes. Mucociliary clearance by PRMC was consistently absent in most PCD patients, regardless of genotype. However, a single patient with a Conclusion: Absent mucociliary clearance by PRMC should be expected in PCD regardless of genotype but residual ciliary function could result in measurable PRMC. This indicates a potential for PRMC to detect improvements in ciliary function if this can be restored. Addressing involuntary cough and peripheral deposition of radioaerosol is important if PRMC is to be used as an outcome measure in future clinical PCD trials.
