Published Workflows

Objective: Systematically synthesize clinical evidence on TPS effects on cognition, motor function, mental health, and safety across neurological and psychiatric disorders.

Why it works: The review first identifies relevant studies across multiple databases, then applies independent study selection and data extraction before formal quality assessment, allowing outcome synthesis to be interpreted in light of study quality and bias.

Stages

  1. 1.
    Literature search(in_silico_filter)

    To identify the available TPS literature across databases before screening and synthesis.

    Selection: Searches were conducted in MEDLINE, PsycINFO & PsycArticles, CENTRAL, Web of Science, and Google Scholar for the period January 2013 to December 2024.

  2. 2.
    Study selection(decision_gate)

    To narrow the search results to studies eligible for inclusion in the review.

    Selection: Two independent reviewers conducted the study selection.

  3. 3.
    Data extraction and quality assessment(functional_characterization)

    To collect outcome and safety data in a structured way and assess study quality before interpretation.

    Selection: Two independent reviewers conducted the data extraction and quality assessment.

  4. 4.
    Risk-of-bias assessment by study design(counter_screen)

    To evaluate internal validity using tools matched to study design before drawing conclusions about TPS effects.

    Selection: RoB2 was used for randomized studies and ROBINS-I for non-randomized studies.

  5. 5.
    Outcome synthesis and interpretation(confirmatory_validation)

    To summarize whether TPS appears promising while explicitly accounting for study limitations.

    Selection: Included studies were synthesized for cognitive, motor, mental health, and safety outcomes.

Steps

  1. 1.
    Search multiple literature databases over a defined date range

    Capture the available TPS evidence base across relevant bibliographic sources.

    Broad retrieval must occur before any study selection, extraction, or quality assessment can be performed.

  2. 2.
    Use two independent reviewers for study selection

    Determine which retrieved studies are eligible for inclusion.

    Selection follows retrieval so that only eligible studies move into extraction and synthesis.

  3. 3.
    Use two independent reviewers for data extraction and quality assessment

    Collect study outcomes and assess study quality in a structured manner.

    Extraction and quality assessment require a finalized included-study set from the prior selection step.

  4. 4.
    Apply RoB 2 to randomized studies and ROBINS-I to non-randomized studiesrisk-of-bias assessment tools

    Assess bias using a tool matched to study design.

    Design-specific bias assessment is performed after studies are identified and extracted so that interpretation can be conditioned on study quality.

  5. 5.
    Synthesize efficacy and safety outcomes while accounting for study limitations

    Generate a review-level conclusion about TPS effects and safety.

    Synthesis comes after extraction and bias assessment so conclusions can be interpreted in the context of evidence quality.

Implementation Constraints

cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensor

The abstract only supports that non-randomized studies are required as inputs for ROBINS-I assessment.; applies to non-randomized studies

Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
