1 · What the graph read from it

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.

2 · The registry

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

objectivesTo characterize the clinical and genetic spectrum of genodermatoses in Southwestern Saudi Arabia, the present study examines the impact of consanguinity on this particular population, and proposes a tailored premarital genetic screening protocol.

methodsA retrospective cross-sectional study of 32 patients diagnosed with genodermatoses during the study period at a tertiary hospital (King Khalid Hospital, Najran) were included. Genetic screening was performed for patients with suspected genodermatoses based on clinical findings, using whole-exome sequencing (WES), specifically employing next-generation sequencing (NGS) technology. Clinical and genetic analysis data were extracted from medical records.

resultsAmong 32 patients diagnosed with genodermatoses, the majority were aged 1-10 years (50%), male (56.3%), and Saudi nationals (87.5%). Autosomal dominant inheritance was most prevalent (56.3%), followed by autosomal recessive and X-linked patterns (each 15.6%). Consanguinity was observed in 71.9% of cases, predominantly first-degree (53.1%). Twenty distinct genodermatoses were identified, with Ichthyosis Vulgaris being the most frequent (15.6%). Consanguinity showed a strong association with genodermatosis subtype (adjusted

conclusionConsanguinity contributes to a higher burden of autosomal dominant genodermatoses in Southwestern Saudi Arabia. Implementation of a premarital targeted genetic screening, integrated with culturally sensitive counseling and feasibility considerations, may reduce disease incidence and associated healthcare costs.
