Haptoglobin genotypes and malaria comorbidity in breast cancer and healthy Nigerian women.
Article in Annals of African medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Breast cancer is the leading cause of mortality among women, with over a million cases recorded globally. Haptoglobin (Hp) protein and genotypes play important roles in cancer predisposition and progression, but studies have reported varying outcomes in populations. Aim: The association of Hp genotypes in breast cancer patients with malaria has not been investigated in Nigerians, which is the aim of our study. In healthy women (control; n = 279) and clinically diagnosed breast cancer patients (breast cancer; n = 70). Methods: Haptoglobin genotypes and Plasmodium falciparum cyclooxygenase III genes were detected by polymerase chain reaction (PCR). Proportions were compared, and the test of association was carried out with a significance level set at P < 0.05. Results: Overall, 311 of 349 (89%) individuals had malaria infection with similar proportions in breast cancer (63 of 70) and healthy control group (248 of 279); malaria incidence was, however, lower in Hp 2-2 breast cancer patients (P = 0.04). The prevalence of Hp genotypes was Hp 1-1 (78.2%), Hp 2-1 (7.2%), and 2-2 (14.6%). In breast cancer groups, Hp 2-2 genotype was significantly lower with 3 (4.2%) of 70 vs. 48 (17.2%) of 279 in control group (P = 0.006). Conclusions: The results of the study show low Hp 2-2 genotype relative to other genotypes in breast cancer patients; we conclude that low Hp 2-2 genotype is associated with lower malaria risk in breast cancer Nigerian women. It is important to further understand the roles malaria, Hp, and other genotypes play in the pathogenesis of aggressive breast cancer commonly seen in Nigerian women.
