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

objectivesThis study examined whether recent changes in smoking prevalence among pregnant women have affected risks of small-for-gestational-age births.

methodsWith data for all live single births in Sweden from 1983 through 1992 (n = 1048139), odds ratios [ORs] and attributable risks of small-for-gestational-age births were calculated for 1983 through 1985, 1986 through 1989, and 1990 through 1992.

resultsDaily smoking decreased from 29.4% in 1983 to 21.8% in 1992. For the three time periods, the odds ratios of small-for-gestational-age births by maternal smoking were almost identical: 1-9 cigarettes/day OR = 2.1 or 2.2; for > or = 10 cigarettes/day, OR = 2.8. The attributable risk of smoking for small-for-gestational-age births declined from 26.2% in 1983 through 1985 to 20.9% in 1990 through 1992.

conclusionsThe findings point to a true decrease in tobacco exposure during pregnancy and a reduction in the attributable risk for small-for-gestational-age births.
