1 · What the graph read from it

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.

2 · The registry

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

Human immunodeficiency virus-exposed but uninfected infants (iHEU) display altered immunity and are at increased risk of infection. We previously reported that iHEU have decreased maternal microchimerism (MMc)-maternal cells transferred to the offspring in utero/during breastfeeding. We quantified MMc in T-cell subpopulations in iHEU and HIV-unexposed infants (iHU) to determine whether a selective deficiency in MMc contributes to altered cellular immunity. Across all infants, MMc levels were highest in CD8+ T cells; however, the level of CD8+ T-cell MMc was lower in iHEU versus iHU. In limited functional studies, we did not identify cytomegalovirus-specific MMc during infant primary infection.
