CCR5-Δ32 gene variant frequency in the Nigerian and Zimbabwean populations living in North Cyprus.
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 2 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: The cystine-cystine chemokine receptor 5 (CCR5) is the primary HIV co-receptor involved in the viral entry process into human cells. The 32 bp deletion variant within the CCR5 gene (CCR5-Δ32) plays a very important role in viral recognition and progression of AIDS. Objective: The current study was aimed at evaluating the CCR5-Δ32 gene variation frequency in Nigerian and Zimbabwean populations residing in Northern Cyprus. Methods: A total number of 211 subjects (103 Nigerians and 108 Zimbabweans) were analyzed. Nigerian population was further analyzed with respect to the three major ethnicities: Igbo, Hausa, and Yoruba. Polymerase Chain Reaction was used to determine the CCR5-Δ32 gene variant status. Results: All studied subjects from both sampling groups were homozygous for the CCR5 wild type gene (CCR5-wt), meaning neither heterozygous nor homozygous genotypes of CCR5-Δ32 gene variant were observed. Conclusion: This study observed the absence of CCR5-Δ32 deletion gene in the Nigeria and Zimbabwean populations living in Northern Cyprus. These populations lack the genetic advantage over HIV infection and may also show a rapid progression towards AIDS. Additionally, these populations could impact the local gene frequency as these two populations interact more and more.
