Participants notes | — |
Modality | fMRI |
Is the study cross-sectional or longitudinal? | Longitudinal—chronic treatment |
If longitudinal, at what time point(s) were imaging data acquired? | T1: pre-treatment/chronic; T2: post-treatment, ~10 weeks later |
If longitudinal, was there any intervention between the time points? | Acupuncture, 3 sessions/week, 8 weeks |
Is the scanner described? | No (not stated) |
Is the timing of stimulus presentation and image acquisition clearly described and appropriate? | No (inconsistent information regarding timing) |

Are the imaging acquisition parameters, including coverage, adequately described and appropriate? | Yes (whole brain) |
Is preprocessing and intrasubject coregistration adequately described and appropriate? | Yes |
Is first level model fitting adequately described and appropriate? | Yes |
Is intersubject normalization adequately described and appropriate? | No (lesion impact not addressed) |
Imaging notes | — |
Language condition | Answering questions from Cantonese Aphasia Battery |
Control condition | Visual decision |
Are the conditions matched for visual demands? | No |
Are the conditions matched for auditory demands? | No |
Are the conditions matched for motor demands? | Yes |
Are the conditions matched for cognitive/executive demands? | No |
Is accuracy matched between the language and control tasks for all relevant groups? | N/A, tasks not comparable |
Is reaction time matched between the language and control tasks for all relevant groups? | N/A, tasks not comparable |
Behavioral data notes | — |
Are control data reported in this paper or another that is referenced? | No |
Does the contrast selectively activate plausible relevant language regions in the control group? | Unknown |
Are activations lateralized in the control data? | Unknown |
Control activation notes | — |
Contrast notes | — |
First level contrast | Answering questions from Cantonese Aphasia Battery vs visual decision |
Analysis class | Longitudinal correlation with language or other measure |
Group(s) | Aphasia T2 vs T1 |
Covariate | Δ WAB AQ |
Is the second level contrast valid in terms of the group(s), time point(s), and measures involved? | Somewhat (no treatment effect) |
Is accuracy matched across the second level contrast? | Unknown, not reported |
Is reaction time matched across the second level contrast? | Unknown, not reported |
Behavioral data notes | — |
Type of analysis | Voxelwise |
Search volume | Whole brain |
Correction for multiple comparisons | Unclear or not stated |
Software | SPM2 |
Voxelwise p | — |
Cluster extent | — |
Statistical details | Stated to be corrected p < 0.05, but the nature of correction is not described; it is not entirely clear whether the functional measure was the difference between T1 and T2 (we assume it is); it is also not clear whether or not 2 patients with low AQ were excluded (we assume not) |
Findings | ↑ L posterior MTG |
Findings notes | Finding based on table; additional small activations are shown in figure but not table |
