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

Accumulation of maternal monocytes in the villous/intervillous space (villitis) is associated with increased risk of perinatal morbidity and mortality and may initiate in utero transmission of cell-associated infectious agents such cytomegalovirus and HIV-1. We have developed an in vitro model of trophoblast syncytialization and have investigated the adhesive interactions between this tissue and peripheral blood monocytes. We show that monocytes strongly adhere to cultured syncytiotrophoblasts (STs) and that treatment with the inflammatory cytokines interferon-gamma, tumor necrosis factor-alpha, and interleukin-1 alpha greatly increase the number bound. Pretreatment of STs with these cytokines upregulated apical expression of intercellular cell adhesion molecule (ICAM)-1 but not E-or L-selection, ICAM-2 or -3, or various integrins. ICAM-1 expression was cytokine concentration dependent, significantly increased within 6 hours of treatment, peaked after 24 hours, and remained undiminished for 48 hours after cytokine removal from the cultures. Adhesion of monocytes to STs was inhibited > 80% by antibody to ICAM-1 or its cognate ligand LFA-1. ICAM-1 was detected immunohistochemically only in rare foci on intact term placental villi. These results suggest that villous trophoblast expression of ICAM-1 occurs only during an immune inflammatory reaction and that aberrant expression of this molecule may be an important pathological feature in those immunoinflammatory disorders of the placenta characterized by an excessive accumulation of leukocytes in the intervillous/villous space such as spontaneous abortion, perinatal hematogenous infections, and villitis of unknown etiology.
