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

introductionDysphagia is common among individuals with Progressive Supranuclear Palsy (PSP). Expiratory muscle strength training (EMST) is a treatment used to increase expiratory muscle force production for airway protection deficits. To our knowledge, no studies have tested EMST in this population. The objective of this study was to determine the feasibility of EMST in individuals with PSP.

methodsTwenty-nine participants completed baseline measures of maximum expiratory pressure and underwent a trial session of EMST. EMST was considered feasible if participants were able to complete at least 10 repetitions at 30% of their maximum expiratory pressure. Qualitative analyses were also completed to investigate types and frequency of clinician support.

resultsTwenty-seven participants (93%) successfully met the criteria for feasibility of EMST. Qualitative analysis revealed 20 individuals required clinician support with most requiring more than one type of assistance.

conclusionsEMST appears to be feasible for most people with PSP though additional clinician support is often required.
