Association between Angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism on the susceptibility to psoriasis and oxidative stress (OS) in a cohort of pediatric psoriatic patients in Sri Lanka: A cross sectional study.

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: Pediatric psoriasis accounts for nearly one-third of the global psoriasis burden. Multiple lines of evidence have shown the relationship between Angiotensin-converting enzyme (ACE) Insertion (I)/deletion(D) polymorphism with psoriasis susceptibility, and oxidative stress (OS) in psoriatic patients. However, such studies, particularly on pediatric psoriasis, are scarce in the local setting. Aims: Our study investigated the prevalence of ACE I/D polymorphism and its associations with oxidative stress in pediatric psoriasis patients in Sri Lanka. Methods: Thirty patients were recruited for this study after obtaining ethical clearance. The polymerase chain reaction was used to explore the ACE I/D polymorphism. Serum Nitric Oxide (NO) levels and the Total Antioxidant Capacity (TAC) were measured using the Griess assay and the FRAP assay. Clinical details were obtained from the clinic reports. Results: Female predominance (76.67%) in pediatric psoriasis was reported, while Plaque psoriasis (66.67%) was found to be the most prevalent form. I/D was reported as the predominant genotype (66.67%) while I/I and D/D genotypes were recorded in 23.33% and 10% of patients, respectively. Significantly higher NO levels were observed in I/D patients than in I/I patients but not among other groups. No differences in TAC among ACE genotypes were reported. Conclusion: This pilot study revealed female gender and I/D genotype with increased NO levels as risk factors for pediatric psoriasis in Sri Lanka. However, it is prudent to increase the sample size to further validate the results.
