IL-4 gene polymorphisms and their association with nematodes infection in Pakistani population.
Article in African health sciences, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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: Interleukin-4 (IL-4) plays a central role in the humoral immune defense against nematode parasite infections, inducing IgE switch and regulation of worm expulsion from the intestines. The present study aimed to investigate the polymorphisms in IL-4 gene and their association with socio-demographic and environmental factors among patients with gastrointestinal complaints. Method: The screened population comprised 305 patients aged 3-50 years from Rawalpindi and Jhelum districts of Pakistan. A well-prepared questionnaire was administered to collect data on socio-demographic and environmental factors. The data were analyzed by using multiple logistic regression models. Molecular analysis was done on 88 confirmed cases passing worms and eggs in stool by using PCR to amplify IL-4 gene. Results: The result showed higher GI nematodes prevalence in Rawalpindi 34.87% and Jhelum 23.1% among gastrointestinal patients. The multivariate logistic regression model showed significantly (p<0.05) increased risk of infection in participants who were residing in rural areas (OR=321.94; 22.5), having poor economic status (OR=0.34), consuming raw/unwashed vegetables (OR=1.73; 15.39) and did not practice handwashing (OR=2.77; OR=0.30). Sequence analysis showed three novel polymorphisms at SNP g.704_705 ins T, g.3763_3764 ins AC and g.3792 G >A in patients with acute severe infections. Two known polymorphisms SNPs g.8455A>G and g.8492C>A were found in the intron region. Conclusion: IL-4 gene polymorphisms showed disease susceptibility and consuming raw/unwashed vegetables, poor handwashing practices and poor economic status were the most associated factors with the disease.
