Intelligence in early adulthood and subsequent risk of assault: cohort study of 1,120,998 Swedish men.
Article in Psychosomatic medicine, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo examine the association between low intelligence (IQ) and increased risk of assault. Previous studies have been relatively small, have not adjust for socioeconomic status, and have not examined method-specific assaults.
methodsCox proportional hazards regression was used to explore IQ associations with assault by any means and by four specific methods in a large prospective cohort of 1,120,988 Swedish men. Study members had IQ measured in early adulthood and were well characterized for socioeconomic status in childhood and adulthood. Men were followed-up for an average of 24 years, and hospital admissions for injury due to assault were recorded.
resultsA total of 16,512 (1.5%) men had at least one hospital admission for injury due to assault by any means during follow-up. The most common assault was during a fight (n = 13,144), followed by stabbing (n = 1,211), blunt instrument (b = 352), and firearms assaults (n = 51). After adjusting for confounding variables, lower IQ scores were associated with an elevated risk of hospitalization for assaults by any means (hazard ratio per standard deviation decrease in IQ, 1.51; 95% confidence interval, 1.49, 1.54) and for each of the cause-specific assaults: fight: 1.48 (1.45, 1.51); stabbing: 1.68 (1.58, 1.79); blunt instrument: 1.65 (1.47, 1.85); and firearms: 1.34 (1.00, 1.80). These gradients were stepwise across the full IQ range.
conclusionsLow IQ scores in early adulthood were associated with a subsequently increased risk of assault. A greater understanding of mechanisms underlying these associations may provide opportunities and strategies for prevention.
