1 · What the graph read from 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.

2 · The registry

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

introductionWe compared the predictive validity of attention deficit hyperactivity disorder (ADHD; Diagnostic and Statistical Manual - IV Edition) and hyperkinetic disorder (HKD; International Classification of Diseases - 10th Edition) while controlling for the presence of comorbid psychopathology.

methodADHD and HKD criteria were used to classify 804 clinic-referred children ages 6 to 16 years into one of four non-overlapping groups: HKD, ADHD combined subtype (ADHD-C), ADHD hyper-active-impulsive subtype (ADHD-HI), ADHD inattentive subtype (ADHD-IA). Groups were compared with each other and with normal controls (67) while controlling for age and intelligence on a range of criteria both before and after excluding cases with comorbidity.

resultsOf the 804 clinic participants, 72 (8.9 %) met criteria for ICD-10 HKD, 353 (43.9 %) for ADHD-C, 142 (17.7 %) for ADHD-HI and 237 (29.5 %) for ADHD-IA. There were no differences among the four clinic groups in rate of comorbidity, neuro-developmental or psychosocial risk indices, inter-parental or parent-child discord, family history of ADHD, working memory, and academic or intelligence test scores, but all clinic groups differed from normal controls. By contrast, total number of symptoms, teacher-rated impairment and inhibitory control deficit were greatest in HKD and least in ADHD-C, ADHD-HI, ADHD-IA in that order. Results of the comparisons were essentially unchanged after excluding cases (75%) with a comorbid condition.

conclusionsHKD, ADHD-C, ADHD-HI and ADHD-IA had approximately equivalent predictive validity even when comorbidity was taken into account.
