Seroprevalence of hepatitis C virus infection in patients with type 2 diabetes mellitus is associated with increased age in sub-Saharan Africa: Results from a cross-sectional comparative analysis.

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: Several epidemiological studies have established the association between hepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM). However, the determinants and reasons for the high prevalence of HCV infection in people with T2DM are not well understood especially in sub-Saharan African populations. In this study, we aimed to assess determinants of the association between HCV infection and T2DM. Methods: We performed a cross-sectional study amongst 442 T2DM patients recruited from an out-patient adult diabetes clinic in a tertiary hospital and 442 non-diabetic controls recruited from the general population. Serological testing for HCV antibody was performed using standard ELISA technique. Anti-HCV antibody prevalence was reported by age group in participants with diabetes and the non-diabetic controls. Logistic regression was used to examine for factors associated with the HCV infection in patients with diabetes. Results: We reported an overall HCV prevalence of 11.5% [95% CI: 9.4-13.6] irrespective of diabetes status in this study. The seroprevalence of HCV infection in diabetics patients was 17.6% [95% CI: 14.0-21.2] compared to 5.5% [95% CI: 3.4-7.6] in non-diabetics (p< 0.001). We did not find a significant HCV seropositivity difference in diabetic patients with common risk factors of HCV infection. When investigating the HCV seroprevalence by age group in diabetic and non-diabetic patients, no case of HCV infection was found in patients less than 30 years old while the highest HCV seropositivity was reported in patients older than 60 years (36.7% T2DM and 11.1% for non-diabetics) followed by the patients belonging to 50-59 years age group (16% in T2DM and 5.8% in non-diabetics) and those in 40-49 years age group (4.4% in diabetic, 0.8% in non-diabetic). To support this finding, in a multivariate logistic regression, only diabetic patients belonging to age group > 65 years had a significant risk (OR: 16.7 [95% CI: 1.7-160.0]) to acquire HCV infection. Conclusion: The seroprevalence of HCV infection is higher among T2DM adult patients than in non-diabetic patients, and is associated with increased age. This age-dependent association may suggest a generational exposure that may no longer exist overtime.
