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

BACKGROUND/

objectivesHomeostatic (nervous, immune and endocrine) systems and their communications network are crucial for health and aging rate. We previously reported behavioral and peritoneal leukocyte function alterations and oxidative-inflammatory stress in young female triple-transgenic (3xTg) mice for Alzheimer's disease (AD). Here, the deterioration of the homeostatic systems and their interplay was investigated, in an integrated way, at prodromal stages and in both sexes of 3xTg-AD mice.

methodsAn integrative analysis of the behavioral profile, peripheral immune splenic and thymic leukocyte functions, splenic oxidative-inflammatory state, and plasmatic corticosterone in both sexes of 3xTg-AD mice at 4 months of age was compared to that of age- and sex-matched NTg counterparts.

resultsThe prodromal stage of 3xTg-AD, characterized by anxiety-like behaviors and disrupted exploration, was aligned with reduced chemotaxis, natural killer activity, and lymphoproliferation-especially in the spleen. In addition, 3xTg-AD mice exhibited lower anti-inflammatory (IL-10) and higher pro-inflammatory (IL-2, IL-1β, and TNF-α) cytokine concentrations and oxidative stress (higher oxidants and lower antioxidants). Several of these alterations displayed sex-dependent differences (worse in males). However, no differences in corticosterone were found.

conclusionsThese findings suggest that neuroimmune and redox-inflammatory dysfunctions, indicative of premature aging, emerge at the prodromal stage of AD, preceding corticosterone changes, unveiling a time lag in the neuroimmunoendocrine alterations in these animals. They may act as early indicators of premature aging in AD pathology and provide potential targets for sex-specific prodromal intervention.
