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

Caesarean section (CS) rates are increasing worldwide. CS and repeat caesarean alter the risk profile for next pregnancy. Interpregnancy interval (IPI) has been shown to modify maternal and neonatal risk in subsequent pregnancies. There is limited research in the Australian context addressing outcomes relative to interpregnancy interval. The lack of pregnancy spacing information adds to confusion and conflicting recommendations for maternity care providers and women. We developed a protocol using data linkage of routinely collected hospital data from 1994 to 2023 in New South Wales, Australia to investigate both maternal and neonatal outcomes relative to interpregnancy intervals.•Large scale study of interpregnancy interval after CS in an Australian multiethnic cohort not previously explored•Quantify the risks associated with differing interpregnancy intervals compared to contemporaneous controls in this cohort•Results presented as absolute risk facilitating access to evidence-based information.
