Impact of genetic counseling and testing in individuals at high risk of familial Alzheimer's disease from Latin America: a non-randomized controlled trial.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionThis study involved evaluating a tailored genetic counseling and testing (GCT) protocol for families at risk of autosomal dominant Alzheimer's disease (ADAD) in Latin America (LatAm), focusing on essential cultural and regional adaptations.
methodsWe conducted a non-randomized controlled trial among ADAD families in Colombia and Argentina. Participants were categorized based on their decision to learn their genetic status (GS), with further comparisons between mutation-positive versus mutation-negative participants who learned their status. Psychological impacts were measured using validated scales for anxiety and depression.
resultsOf the 122 eligible participants, 97 completed the GCT protocol, and 87 opted to learn their GS. There were no clinically significant differences in psychological distress between those who learned their status and those who did not, nor between mutation-positive and mutation-negative individuals. DISCUSSION: The GCT protocol effectively managed psychological impacts in ADAD families and was positively received, demonstrating the importance of culturally adapted GCT protocols. Highlights: We examined the adaptation and efficacy of a GCT protocol in LatAm for families at risk of ADAD.The GCT protocol mitigated psychological distress among at-risk ADAD families.The study confirms the protocol's cultural appropriateness and psychological safety.Future studies should explore the long-term psychological and public health impacts of GCT and use of GCT for treatment options.
