Early Life Stress and Long-Term Survival in the Hamann-Todd Collection.

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
objectivesThe impact of physiological stress during growth and development on mortality has been a topic of intense interest in bioarchaeology and other disciplines. In this study, we analyze the association between survival and two markers of physiological stress, linear enamel hypoplasia (LEH) and adult stature, in a sample of 296 individuals from the Hamann-Todd Osteological Collection (HTOC). MATERIALS AND
methodsThe HTOC is among the most well-known osteological collections in the discipline, representing low socioeconomic status individuals from early 20th century Cleveland, Ohio. Ages-at-death and demographic identifiers (sex and socially ascribed race) were known for all individuals in the sample. The association between the skeletal and dental markers of early life stress and survival was evaluated through Kaplan-Meier survival analysis, using log rank tests to analyze the significance of differences in survival among demographic groups.
resultsSignificant differences in survival were observed between demographic groups, regardless of LEH status or stature. However, there were no significant differences in survivorship by LEH presence in this sample, despite the expectation that periods of physiological stress during key stages of development contribute to long-term health consequences such as suppressed immune function. For females, shorter statures were associated with a higher probability of survival, while there were no significant differences in survival for males based on stature. DISCUSSION: It is likely that differences in survival observed in this sample of the HTOC are the consequence of other factors, most likely related to adult environmental quality, as opposed to early life stress.
