Childhood IQ predicts age-38 oral disease experience and service-use.
Article in Community dentistry and oral epidemiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
objectivesGiven that people with higher intelligence have been shown to live longer, enjoy better health and have more favourable health behaviours, we investigated the association between childhood IQ and a range of important dental health and service-use indicators at age 38.
methodsLong-standing prospective study of a complete birth cohort, with childhood IQ (assessed at ages 7, 9, 11 and 13 years) used to allocate participants (N = 818) to one of four ordinal categories of childhood IQ.
resultsThere were distinct and consistent gradients by childhood IQ in almost all of the dental caries experience measures (with the exception of filled teeth) whereby each was most severe in the lowest child IQ category and least severe in the highest; the exception was the mean FT score, for which there was no discernible gradient. Indicators of self-care and periodontal disease experience showed similar gradients, and multivariate modelling using the continuous IQ score confirmed the observed patterns.
conclusionsChildhood cognitive function is a key determinant of oral health and dental service-use by midlife, with those of lower cognitive capacity as children likely to have poorer oral health, less favourable oral health-related beliefs, and more detrimental self-care and dental visiting practices by age 38. There is a need to shape dental clinical services and public health interventions so that people with the poorest cognitive function do not continue to be disadvantaged.
