Differential cardiac geometry during pregnancy in lean versus obese mice.
Article in Reviews in cardiovascular medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPregnancy is a sensitive window where factors adversely affecting maternal cardiac health may leave women vulnerable to cardiovascular disease (CVD) later in life. However, it is not clear how cardiac changes during pregnancy influence long-term cardiovascular health. Obesity, an independent risk factor for CVD, promotes adverse cardiac remodeling. Effects of obesity-mediated cardiac remodeling concurrent with physiologic cardiac hypertrophy of pregnancy are not well-studied.
methodsFemale C57BL/6J mice (8 weeks old) were fed a high fat (HF; 60% kcal from fat) or a control low fat (LF; 10% kcal from fat) diet for 8 weeks, then were crossed with male mice to become pregnant (P) or remained non-pregnant (NP) controls. After 18 days, cardiac morphology and function was quantified by echocardiography in LF and HF P and NP mice.
resultsLean mice had increased left ventricular (LV) mass and LV end-diastolic diameter with pregnancy. In contrast, although LV mass was greater with obesity, it was not augmented with pregnancy in obese mice. Further, pregnant obese mice had decreased LV chamber diameter and increased relative wall thickness compared to lean mice.
conclusionsWe report a differential cardiac geometry during pregnancy in lean versus obese mice in a mouse model of diet-induced obesity. These data suggest obesity during pregnancy promotes concentric remodeling, versus eccentric remodeling in lean mice. Adverse effects of obesity on cardiac remodeling during pregnancy may be an important contributor to subsequent maternal cardiovascular risk.
