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

objectiveTo investigate whether virtual reality (VR) interventions have beneficial effects on the functional communication and language function of patients with post-stroke aphasia (PSA).

methodsWe searched nine electronic literature databases and two clinical registry platforms to identify randomized controlled trials (RCTs) and quasi-RCTs performed up to September 2020. Screening, quality assessment, and data collection were performed by two authors independently, using standard protocols. Data aggregation and risk of bias evaluation were conducted using Review Manager Version 5.4. The quality of evidence was evaluated with GRADEpro.

resultsA total of five studies involving 121 participants met the inclusion criteria and were appraised. Four studies were included in the quantitative synthesis. VR reduced the severity of language impairment with borderline significance [SMD (95%CI) = 0.70[0.01, 1.39], P=0.05]. The meta-analysis showed no statistical difference in functional communication [SMD (95%CI) =0.41[-0.29, 1.12], P=0.25], word finding [SMD (95%CI) =0.42[-0.24, 1.08], P=0.21], and repetition [SMD (95%CI) =0.16[-0.62, 0.94], P=0.68] between VR group and the control group.

conclusionThis review demonstrated a borderline positive clinical effect of VR for the severity of language impairment when compared with conventional rehabilitation therapy. Conversely, VR had no effect on functional communication, word finding, and repetition. Further research is warranted to reach more definite conclusions.
