Time trends in symptoms of mental illness in children and adolescents in Canada.
Article in CMAJ : Canadian Medical Association journal = journal de l'Association medicale canadienne, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 papers, 1 of them a synthesis that pooled it.
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
backgroundExisting research and media reports convey conflicting impressions of trends in the prevalence of mental illness. We sought to investigate trends in the prevalence of symptoms of mental illness in a large population-based cohort of Canadian children and adolescents.
methodsWe obtained population-based data from the National Longitudinal Survey of Children and Youth. Every 2 years, participants completed self-reported measures of mental illness indicators, including conduct disorder, hyperactivity, indirect aggression, suicidal behaviour, and depression and anxiety. We analyzed trends in mean scores over time using linear regression.
resultsWe evaluated 11 725 participants aged 10-11 years from cycles 1 (1994/95) through 6 (2004/05), 10 574 aged 12-13 years from cycles 2 (1996/97) through 7 (2006/07), and 9835 aged 14-15 years from cycles 3 (1998/99) through 8 (2008/09). The distribution of scores on depression and anxiety, conduct and indirect aggression scales remained stable or showed small decreases over time for participants of all ages. The mean hyperactivity score increased over time in participants aged 10-11 years (change per 2-year cycle: 0.16, 95% CI 0.02 to 0.12) and those aged 12-13 years (0.13, 95% CI 0.09 to 0.18). Over time, fewer participants aged 12-13 years (0.40% per cycle, 95% CI -0.78 to -0.07) and aged 14-15 years (0.56% per cycle, 95% CI -0.91 to -0.23) reported attempting suicide in the previous 12 months.
interpretationWith the exception of hyperactivity, the prevalence of symptoms of mental illness in Canadian children and adolescents has remained relatively stable from 1994/95 to 2008/09. Conflicting reports of escalating rates of mental illness in Canada may be explained by differing methodologies between studies, an increase in treatment-seeking behaviour, or changes in diagnostic criteria or practices.
