Effect of selenium supplementation on HIV-1 RNA detection in breast milk of Tanzanian women.

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
objectiveSelenium supplementation for women infected with HIV may increase genital shedding of HIV-1, however, to our knowledge, no studies have examined the effect on viral shedding in breast milk. The aim of this study was to determine the effect of selenium supplementation on HIV-1 RNA detection in breast milk of HIV-infected women.
methodsHIV-infected pregnant women enrolled at 12 to 27 wk gestation in a randomized, double-blind, placebo-controlled trial of daily selenium (200 μg as selenomethionine) had cell-free HIV-1 RNA quantified in breast milk at 4 to 9 wk postpartum. All participants received high-dose multivitamins containing vitamin B complex, C, and E as standard of care.
resultsThe proportion of women with detectable (>50 copies/mL) HIV-1 RNA in breast milk appeared to be increased in the selenium group (36.4%) compared with those in the placebo group (27.5%) among the total cohort (N = 420), but results were borderline statistically significant (relative risk [RR], 1.32; 95% confidence interval [CI], 1.00-1.76; P = 0.05). In secondary analyses, the proportion of women with detectable HIV-1 RNA in breast milk was significantly greater in the selenium group (37.8%) compared with placebo group (27.5%) among women who did not receive highly active antiretroviral therapy (HAART; RR, 1.37; 95% CI, 1.03-1.82; P = 0.03). This relationship was primarily due to a significant effect of selenium among primiparous women (RR, 2.24; 95% CI, 1.30-3.86; P < 0.01), but not multiparous women (RR, 1.14; 95% CI, 0.81-1.59; P = 0.54) (P-value for interaction = 0.02). Too few women received HAART in this study (n = 12) to establish the effect of selenium supplementation.
conclusionsSelenium supplementation appears to increase HIV-1 RNA detection in breast milk among primiparous women not receiving HAART. Safety studies among pregnant women on HAART need to be conducted before administering selenium-containing supplements.
