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

This case series examined qualitative differences in discourse impairment in two elderly right-handed female patients (one in her 60s and another in her 70s) with right hemisphere damage (RHD) and explored the potential involvement of theory of mind (ToM). Patients with RHD often present with discourse-level communication disorders despite relatively preserved basic language abilities. However, the nature of such discourse impairments is not uniform. Discourse performance was assessed using a four-frame cartoon description task, and ToM was evaluated using the Strange Stories test. Case A demonstrated relatively preserved inferential discourse despite making errors in event-related statements, whereas Case B showed prominent impairments in inferential discourse accompanied by marked ToM deficits. These contrasting profiles suggest that discourse impairment following RHD may arise through different underlying mechanisms, with ToM-related processes contributing to inferential discourse disturbances in some individuals.
