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

backgroundOur aim was to examine if a prepregnancy lifestyle intervention impacted early childhood weight gain.

methodsA 5-year longitudinal observational follow-up of children born to women aged 18-40 years with body mass index (BMI) ≥27 kg/m

resultsOf the 165 children born to Prepare participants, 133 (70 in intervention and 63 in usual care) contributed BMI data to the PrepareD observational follow-up study. Longitudinal BMI trajectories from birth to age 5 demonstrated no significant differences between study arms (

conclusionsA prepregnancy lifestyle intervention did not influence childhood weight trajectory. Focusing lifestyle interventions solely on prepregnancy maternal obesity may not be sufficient to influence childhood growth. Trials that examine lifestyle interventions that offer support before, during, and after pregnancy are needed to determine if intervening before conception can interrupt the intergenerational cycle of obesity.
