Seroprevalence and factors associated with Human Immunodeficiency virus, Human T lymphotropic virus and Hepatitis B/C infections in parturient women of Salvador - Bahia, Brazil.

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
backgroundThe heterogeneity in detection rates of Human immunodeficiency virus, (HIV), Human T lymphotropic virus (HTLV) and Hepatitis B and C infections among pregnant women and the continuous exposure to risk factors limits the adoption of preventive and control actions.
objectiveTo evaluate the HIV, HTLV, Hepatitis B and C seroprevalence rates, and associated risk factors in parturient women in Salvador, Brazil.
methodsThis was a cross-sectional study in 2099 parturient women attended in two public maternity hospitals in Salvador, Brazil. One blood sample was drawn for serological screening and socio-demographic, obstetric and clinical data were collected.
resultsHIV seroprevalence rate was 1.5% (of which 0.6% were new cases); seroprevalence rates for HTLV, HBV, and HCV were 0.4%, 0.4%, and 0.1%, respectively. Univariate analysis showed a significant association between socio-demographic and behavioral factors with retroviral infections, while viral hepatitis was mainly associated with parenteral exposure. In a multivariate analysis, multiple sexual partners (OR 3.3; 95% CI: 1.1-9.2), history of sexual/domestic violence (OR 2.8; 95% CI: 1.1-6.9), syphilis co-infection (OR 2.6; 95% CI: 1.0-6.9), use of alcohol or drugs (OR 2.5; 95% CI: 1.2-5.5), and low schooling level (OR 2.3; 95% CI: 1.1-4.9) were independent risk factors for HIV infection. History of stillbirth and low birth weight infants was significantly associated with HTLV positive status, showing a negative impact on gestation.
conclusionsThe seroprevalence rates for HIV, HCV, HBV, and HTLV were similar to that found in previous studies in other Brazilian regions. The high individual, socioeconomic, and social vulnerability detected in seropositive parturient women indicates the need to improve coverage and effectiveveness of STDs control with prevention, detection and monitoring strategies, focusing in pregnant women exposed to high biopsychosocial risk.
