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
Tooth loss among indigenous people in the Amazon emphasizes the need for culturally appropriate oral health interventions. The objective of this study was to analyze the incidence of tooth loss in two remote Amazon indigenous populations. This prospective cohort evaluated a total of 47 indigenous in the permanent dentition at T0 and thirteen years later (T1) from two villages, Arara-Laranjal (n = 28, mean age 16.1 and 29.9 years) and Assurini do Xingu (n = 19, mean age 15.9 and 29.5 years), of different ethnic groups. A multilevel Poisson regression model assessed the influence of village, sex, and age on tooth loss. At T0, the indigenous people had all their permanent teeth. Forty-two lost at least one tooth (89%), and a total of 172 teeth were lost at T1 at an incidence of 97% among females and 76% in males. There was no influence of ethnicity on tooth loss (
