Porphyria Cutanea Tarda: A Phenotypic Expression of Several Genes.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Porphyria comprises a group of rare inherited or acquired disorders characterized by defects in the heme biosynthetic pathway, resulting in the accumulation of porphyrins or their precursors. This study presents three cases of porphyria in Puerto Rico, including erythropoietic protoporphyria (EPP) and porphyria cutanea tarda (PCT). Genetic testing revealed a heterozygous mutation in the FECH gene in the EPP case and an HFE gene mutation in a PCT case with hereditary hemochromatosis. A previously undocumented case of PCT with elevated uroporphyrin levels but negative genetic panel results raises questions about the genetic basis of porphyria. Our findings highlight the importance of genetic testing in diagnosing and managing porphyria, emphasizing the need for further research into its genetic and phenotypic diversity. This study contributes to the understanding of porphyria in Puerto Rico, offering insights into its clinical and genetic complexities.
