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

purposeAphasia is a communication disorder that affects up to 30% of stroke survivors. Insufficient access to communication services creates personal, social, and financial costs to people with aphasia (PwA), care partners, and the community. Group conversation treatment has the potential to improve communication and reduce social isolation in a cost-effective manner, but little is known about its critical ingredients. This multicenter randomized controlled trial examined the effects of conversation treatment and whether the pattern of changes on outcome measures differed when treatment was delivered in large groups compared to dyads.

methodOne hundred four PwA were randomly assigned to a dyad, large group, or delayed control condition. Conversation group treatment was 1 hr, twice weekly, over 10 weeks. Individual communication goals were addressed within thematically oriented conversation treatment. To evaluate treatment effects, primary (Aphasia Communication Outcome Measure [ACOM]) and secondary outcome measures were examined at pretreatment, posttreatment, and 6 weeks posttreatment.

resultsThe ACOM did not show significant changes in the planned omnibus analyses. Post hoc analyses suggested that the large group, but not dyad, treatment condition showed a treatment effect on the ACOM from pre- to posttreatment. Both treatment conditions showed changes on a measure of naming, and the dyads also showed improvement on a measure of repetition.

conclusionsThe study failed to show the effects of conversation treatment in the omnibus analysis, but there was evidence that conversation group treatment, delivered in a large group, is effective for people with chronic aphasia. This study also illustrated how manipulating the size of the group may alter the outcomes for individuals. The results of this study offer support for a SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.28719578.
