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

backgroundThis study was designed to determine whether the occurrence of clubfoot follows a seasonal pattern in neonates from eastern and south-eastern China and to speculate the potential etiology of clubfoot.

methodsWe reviewed 239 neonates with clubfeet during a period of 4 years as well as the monthly neonatal population of the Sixth National Population Census. Seasonal variations in terms of month of birth and severity were analyzed.

resultsThe incidence of clubfoot in neonates from eastern and south-eastern China showed seasonal variations, and the incidence was higher in autumn with a reference to the average birth rate in this corresponding area. No significant difference was found in severity of clubfoot.

conclusionsThis seasonal pattern is of significant value to further understanding the etiology and pathogenesis of clubfoot in the corresponding area of China.
