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

purposeHigher maternal parity and younger maternal age have each been observed to be associated with subsequent offspring suicidal behaviour. This study aimed to establish if these, and other variables from the perinatal period, together with family size, are also associated with other psychiatric morbidity.

methodsLinked datasets of the Scottish Morbidity Record and Scottish death records were used to follow up, into young adulthood, a birth cohort of 897,685. In addition to the index maternity records, mothers' subsequent pregnancy records were identified, allowing family size to be estimated. Three independent outcomes were studied: suicide, self-harm, and psychiatric hospital admission. Data were analysed using Cox regression.

resultsYounger maternal age and higher maternal parity were independently associated with increased risk in offspring of suicide, of self-harm and of psychiatric admission. Risk of psychiatric admission was higher amongst those from families of three or more, but, compared with only children, those with two or three siblings had a lower risk of self harm.

conclusionPerinatal and family composition factors have a broad influence on mental health outcomes. These data suggest that the existence of younger, as well as elder siblings may be important.
