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

objectivesCompared to other racial/ethnic groups, Native Americans (NAs) are more likely to develop health conditions associated with allostatic load (stress-related wear-and-tear). Psychosocial factors (i.e., adverse life events, discrimination, psychological distress) often promote stress and may help explain greater allostatic load in NAs. Moreover, previous research suggests sleep may either mediate or moderate the effects of some psychosocial stressors, like discrimination, on allostatic load. The current study investigated the relationship between adverse life events, discrimination, psychological stress, sleep, and cardiometabolic load.

methodsUsing a sample of 302 healthy, chronic pain-free NAs and non-Hispanic White (NHW) participants, bootstrapped mediation analyses were conducted to determine whether the relationship between NA race/ethnicity and cardiometabolic allostatic load (composite score of body mass index, mean arterial pressure, and heart rate variability) was mediated by psychosocial stressors. Models also assessed whether sleep disturbance served as an additional mediator or a moderator to the effects.

resultsConsistent with prior research, we found that NAs experienced greater discrimination, adverse life events (potentially traumatic events), and cardiometabolic allostatic load than NHWs. Further, discrimination was associated with increased psychological stress for NAs, but this did not explain why NAs experience higher cardiometabolic allostatic load. A moderating effect of sleep on discrimination was found, such that discrimination partially contributed to the relationship between NA race/ethnicity and cardiometabolic allostatic load, but only for participants reporting greater sleep disturbance. Implications These findings highlight that good sleep can buffer the effect of psychosocial stress on cardiometabolic allostatic load in Native Americans.
