Sex differences in cardiac remodeling after kidney transplantation.
Article in BMC nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCardiovascular diseases are the most frequent causes of death in patients with chronic kidney disease. Patients with chronic kidney disease often have heart remodeling with left ventricular hypertrophy, left atrial enlargement, and diastolic and systolic dysfunction which reverse after kidney transplantation. Since sex hormones modulate heart histology and physiology, this study aims to know whether the remodeling changes of the heart after a kidney transplant according to sex.
methodsA prospective study was carried in recipients of a kidney graft followed-up from transplant to three and six months after. Biochemical and echocardiographic parameters were obtained and differences between sexes analyzed. The comparison of the studied parameters was made by two way ANOVA considering sex and months of follow-up. A value of p < 0.05 was considered significant.
resultsFifty-one patients were studied, 19 women and 32 men (mean age 31.16 ± 9.83 vs. 31.66 ± 9.63 years, p 0.86). The Left ventricular hypertrophy showed differences according to sex at baseline, men had higher left ventricular mass index than women (male 152.94 ± 58.24 Vs. women 103.89 ± 29.94 g/m2, p = 0.000), as well as during follow-up. Men had a more significant reduction in the left ventricular mass index compared to women (p = 0.000). The left atrial volume index was found to be langer at baseline in women compared to men (45.18 ± 29.77 Vs. 29.05 ± 9.30 ml/m2, p = 0.028). At follow-up, the size reduction was more significant in women (p = 0.000).
conclusionThere was a difference in cardiac remodeling after renal transplant according to sex.
