Impact of Consanguinity and Familial Aggregation on Vitiligo Epidemiology in Saudi Arabia: A Case-Control Study.
Article in Cureus, 2024. 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
Background Vitiligo, characterized by depigmented patches due to melanocyte loss, involves genetic, autoimmune, and environmental factors. Recent studies suggest a link between family history, consanguinity, and vitiligo prevalence, particularly in regions with prevalent consanguineous marriages. This study explored the relationship between consanguinity and familial vitiligo prevalence in Saudi Arabia. Methods A case-control study enrolled 792 participants from Saudi dermatology clinics (382 vitiligo cases, 408 controls). Family histories and consanguinity levels were assessed. Logistic regression analysis, adjusting for relevant variables, evaluated associations. Results Significant associations were found between vitiligo and both parental consanguinity and family history. Cases had higher consanguinity rates, with 246 out of 382 (64.4%), compared to controls, with 161 out of 408 (39.5%). A positive family history of vitiligo was more common in cases, with 184 out of 382 (48.2%) than in controls, with 90 out of 408 (22.1%). Logistic regression identified parental consanguinity and positive family history as significant risk factors for vitiligo, with adjusted odds ratios (aOR) of 2.39 and 2.92, respectively. Their synergistic effect notably amplified the risk (aOR = 7.58), indicating a complex genetic and familial influence on vitiligo in Saudi Arabia. Conclusions Consanguinity showed a significant association with vitiligo prevalence, highlighting genetic factors' role. Further genetic research is needed to identify specific mutations in vitiligo among consanguineous populations. Genetic counseling and awareness programs are crucial in regions with high consanguinity rates to mitigate vitiligo and other genetic disorders' risks.
