The MASCC COG-IMPACT: An unmet needs assessment for cancer-related cognitive impairment impact developed by the Multinational Association of Supportive Care in Cancer.

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.
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
purposeCancer-related cognitive impairment (CRCI) can have a profound impact on the lives of cancer survivors. A multitude of subjective and objective assessment tools exist to assess the presence and severity of CRCI. However, no purpose-built tool exists to assess the unmet needs of cancer survivors directly relating to CRCI. This paper details the development and initial validation of the Multinational Association of Supportive Care in Cancer - Unmet Needs Assessment of Cancer-Related Cognitive Impairment Impact (the MASCC COG-IMPACT).
methodsA multistep mixed-methods measurement development and validation approach was taken with a strong emphasis on co-design. Qualitative interviews were conducted with cancer survivors (n = 32) and oncology health professionals (n = 19), followed by a modified Delphi survey with oncology health professionals (n = 29). Cognitive interviews with cancer survivors (n = 22) over two rounds were then conducted to finalise the penultimate version of the unmet needs assessment tool for CRCI. Four-hundred and ninety-one (n = 491) cancer survivors then completed the MASCC COG-IMPACT and other established measures to inform structural, reliability, validity, acceptability, appropriateness, and feasibility analyses.
resultsThe final MASCC COG-IMPACT is a 55-item and eight subscale tool including two indices: "difficulties" and "unmet needs". The MASCC COG-IMPACT was found to have strong structural validity, convergent validity, discriminant validity, internal consistency, and test-retest reliability. The MASCC COG-IMPACT was also found to be highly acceptable, appropriate, and feasible.
conclusionThe MASCC COG-IMPACT may facilitate optimal care and referral in line with a cancer survivor's CRCI-related difficulties and unmet needs. The MASCC COG-IMPACT may also be used to explore factors and contributors to CRCI-related difficulties and unmet needs. Overall, the MASCC COG-IMPACT is a highly reliable and valid tool for the assessment of CRCI-related difficulties and unmet needs in both clinical and research settings.
