Is time post stroke onset reported and appropriate to the study design? | Yes (subacute: range 0.5-3 months; chronic: range 17-40 months) |
To what extent is the nature of aphasia characterized? | Comprehensive battery |
Language evaluation | AAT, ANELT |
Aphasia severity | T1: subacute: ASRS median 1, range 0-2; ANELT range 10-29; chronic: ASRS median 1.5, range 1-2; ANELT range 20-29; T2: subacute: ASRS range 1-3; ANELT range 10-43; chronic: ASRS range 1-2; ANELT range 22-31 |
Aphasia type | T1: all severe non-fluent; T2: not stated |
First stroke only? | Not stated |
Stroke type | Not stated |
To what extent is the lesion distribution characterized? | Extent and location |
Lesion extent | Subacute: range 32.4-141.2 cc (no lesion extent was reported for one subacute participant because there was no tissue loss yet); chronic: range 27.4-87.9 cc |
Lesion location | 8 L MCA, 1 L SMA and R insular-temporoparietal |
Participants notes | — |
Modality | fMRI |
Is the study cross-sectional or longitudinal? | Longitudinal—mixed |
If longitudinal, at what time point(s) were imaging data acquired? | T1: pre treatment/subacute or chronic; T2: post-treatment, ~6 weeks later |
If longitudinal, was there any intervention between the time points? | MIT, 5+ hours/week |
Is the scanner described? | No (GE 3 Tesla; model not stated) |
Is the timing of stimulus presentation and image acquisition clearly described and appropriate? | Yes |
Design type | Block |
Total images acquired | 132 |
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) |

Contrast notes | — |
First level contrast | Listening to narrative speech vs listening to reversed speech |
Analysis class | Cross-sectional correlation with language or other measure |
Group(s) | Aphasia T1 |
Covariate | Lesion volume |
Is the second level contrast valid in terms of the group(s), time point(s), and measures involved? | Yes |
Is accuracy matched across the second level contrast? | N/A, no behavioral measure |
Is reaction time matched across the second level contrast? | N/A, no timeable task |
Behavioral data notes | — |
Type of analysis | Region of interest (ROI) |
ROI type | Laterality indi(ces) |
How many ROIs are there? | 1 |
What are the ROI(s)? | Language network LI |
How are the ROI(s) defined? | Activations that were "not clearly related to known language areas" were excluded, but the basis for this determination is not clear |
