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

In a randomised controlled trial intensive individual anti-smoking advice given in parallel with hospital antenatal care did not influence the outcome of pregnancy. The belief that retardation of fetal growth caused by maternal smoking occurs in late pregnancy is not well based, and the advice may not have been given in time to be effective. Other possible interpretations of the results, that maternal smoking is merely an index of some other factor that retards growth or that those counselled did not reduce their smoking sufficiently to influence outcome, cannot be excluded.
