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

Pregnancy represents a dynamic immunological state in which the maternal immune system must balance tolerance toward the semi-allogeneic fetus while maintaining antimicrobial defense. Cytomegalovirus (CMV) infection is highly prevalent worldwide and profoundly shapes immune cell differentiation and long-term activation in adults. However, its interaction with pregnancy-associated immune remodeling remains incompletely defined. In this prospective longitudinal study, we comprehensively analyzed immune profiles of healthy pregnant women across all three trimesters and age-matched nonpregnant controls, stratified by CMV IgG serostatus. Multiparametric flow cytometry characterized T and B cell subsets and cytokine production following in vitro stimulation, while circulating cytokines and adhesion molecules were quantified using multiplex immunoassay. Gestational age was the primary determinant of leukocyte dynamics. Nevertheless, CMV-seropositive pregnant women showed enhanced activation and differentiation of CD4
