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.
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
Maternal nutrition during offspring development influences the offspring physiology and risk of long-term chronic disease. Here, we investigate the effects of maternal high-fat diet during distinct developmental windows (preimplantation alone, EmbHFD; or throughout gestation and lactation, HFD) on adult offspring metabolic, molecular and motor behavioural outcome. Our mouse model, utilising healthy nonobese MF1 mothers, induced distinct offspring outcomes dependent upon dietary duration with some sex-specific effects. EmbHFD offspring had high serum leptin (females), elevated systolic blood pressure (SBP), low locomotory activity and diminished motor coordination. Similarly, HFD offspring not only had raised serum leptin, high SBP and poor motor coordination but also experienced excess weight gain, deficits in energy metabolism, reduced relative brown adipose tissue (BAT) mass (females) and increased muscle lipid accumulation. Transcriptomic profiling of HFD female offspring revealed upregulation of thermogenic and lipid-handling genes (e.g.,
