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
We hypothesized that in dairy cattle maternal energy restriction applied during two gestational windows (up to day 80 or 120 of gestation) impairs ovarian and cardiovascular development in juvenile female offspring. We also investigated the role of maternal leptin and testosterone in developmental programming in calves. Holstein-Friesian heifers were randomly assigned to one of three experimental groups; starting 10 days before artificial insemination, they were individually fed at (i) 0.6 of their maintenance energy requirements (M) up to day 80 (Nutrient Restricted, NR80) or (ii) day 120 of gestation (NR120); (iii) 1.8 M until day 120 of pregnancy (Control). Plasma leptin concentrations increased transiently in nutritionally restricted heifers pregnant with a single female calf, but maternal testosterone concentrations were not influenced by diet. Calves had similar body growth, but daughters of NR80 and NR120 had impaired ovarian development, as assessed by reduced gonadal weight, fewer surface antral and primary follicles, and recovered cumulus-oocyte complexes, as well as lower circulating anti-Müllerian hormone concentrations. Cardiovascular morphology and function in the offspring were not influenced by maternal diet, as determined by peripheral arterial blood pressure, echocardiography, post-mortem heart weight, and aortic circumference. Regardless of its duration (until day 80 or 120 of gestation), nutritional restriction resulted in a similar alteration of ovarian development in juvenile progeny, but cardiovascular development was unaltered. Evidence suggests that the window of development that encompasses the peri-ovulatory period to the first 2.6 months of gestation is critical in ovarian programming and that maternal leptin may be involved.
