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

objectiveRegulatory T lymphocytes mediate homeostasis of the immune system and differentiate under the control of the transcription factor FoxP3 in the fetal thymus. We asked whether fetal inflammation caused by chorioamnionitis would modulate thymus development. STUDY

designFetal sheep were exposed to an intraamniotic injection of 10 mg lipopolysaccharide at 5 hours, 1 day, 2 days, or 5 days before delivery at 123 gestation days. Cord blood lymphocytes, plasma cortisol, and thymus weight were measured. Glucocorticoid receptor-, activated caspase-3-, Ki-67-, proliferating cell nuclear antigen-, nuclear factor-kappaB-, and FoxP3-positive cells were immunohistochemically evaluated in thymus.

resultsIntraamniotic lipopolysaccharide exposure decreased the number of circulating lymphocytes by 40% after 1 day. Thymus-to-body weight ratios were reduced in all lipopolysaccharide groups by a maximum of 40% at 5 days. Lipopolysaccharide exposure modestly increased plasma cortisol concentration, increased nuclear factor-kappaB immunostaining in fetal thymus and reduced the number of FoxP3-positive cells by 40% at 1 day.

conclusionIntraamniotic exposure to lipopolysaccharide induced thymic changes and influenced thymic FoxP3 expression.
