Validity of laser induced breakdown spectroscopy (LIBS) in determining age and sex from tooth specimens.
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: To determine age and sex from tooth specimens using Laser-Induced Breakdown Spectroscopy (LIBS). Materials and methods: A total of 170 human teeth samples between age of 15-86 years of both male and female sex were obtained for the study based on the inclusion and exclusion criteria. All the tooth samples were mounted and ground sections of about 1.5-2 mm thickness were prepared. Each tooth sample was subjected to LIBS along the cemento-enamel junction and spectrographs were acquired that denoted the elemental presence in each tooth sample. Results: The elemental concentration of Ca I, Ca II, P and Fe in all the teeth samples declined as the age progressed. The Peak intensity of Ca, P and Fe was observed in the second decade of life. The overall concentration of Fe exhibited highest intensity in both male and female samples when compared with other elements assessed. The general concentration of all the elements were relatively higher in the female samples when compared to those in males. Conclusion: The CEJ seems to be a better site for elemental analysis of tooth since multiple tooth sites are represented in this region and the other sites of teeth such as enamel or roots of teeth may tend to get fractured, and my not be available for the analysis. The signal intensities of trace elements seen to reduce with increase in age. However, certain external factors also seemed to have an influence on these outcomes.
