Microglia reactivity is brain region and sex specific in the context of chronic stress.

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.
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
Chronic stress has been associated with an increased inflammatory profile in the brain, linking inflammation to the development of stress-related disorders. Although the detailed mechanism connecting chronic stress to inflammation remains unclear, as primary mediators of the immune response, it has been established that microglia play a role. We further investigated the effect of chronic stress on microglia reactivity by incorporating sex and multiple brain regions as variables in our analysis. We utilized the unpredictable chronic mild stress (UCMS) paradigm and then quantified the number of microglia, process arborization, process length, and the number of processes of microglia in the prefrontal cortex (PFC), nucleus accumbens (NAC), hypothalamus (HYPO), amygdala (AMY), and hippocampal CA1 and CA3. We did not observe a stress-induced change in the number of microglia in each region; however, chronic stress reduced microglia arborization, length, and number of processes in a brain region and sex-specific manner. Independent of stress, microglia exhibited a region-dependent reactive phenotype. Together, chronic stress affects microglia reactivity uniquely based on sex and brain region, while the different reactivity profile of microglia in males and females might underlie the sex-specific mechanism of the diseases.
