Periodontitis and diabetes in pregnant rats: Maternal-fetal outcomes.
Article in Heliyon, 2024. 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
Aim: To evaluate the repercussions of periodontitis and diabetes association on rat pregnancy and newborns. Methods: Diabetes was induced in female Wistar rats 24 h after birth through the administration of Streptozotocin. The diabetic condition of the rats was further confirmed in adulthood. After mating, the pregnant rats were distributed into four experimental groups (n = 12 rats/group): nondiabetic and diabetic with and without periodontitis. Periodontitis was induced by a ligature inserted into the first molar on day 0 of pregnancy. Body weight, water and feed consumption were evaluated weekly, and an oral glucose tolerance test was performed on day 17 of pregnancy. On day 21 of pregnancy, the animals were anesthetized and killed for organ removal. The hemimandibles were collected to analyze alveolar bone loss. Immunological and biochemical parameters were evaluated in the maternal blood samples, and reproductive performance was analyzed. The newborns were weighed, and anomalies evaluated. Results: The group with diabetes and periodontitis had a greater degree of alveolar bone loss, along with higher relative pancreatic weight, blood glucose levels, triglyceride and inflammatory cytokine levels, hepatic transaminase activity, and embryonic losses. In addition, these newborns had increased body weight, placental weight, a greater number of ossification centers, and a higher rate of visceral and skeletal anomalies. Conclusion: The combination of maternal diabetes and periodontitis negatively impacts maternal parameters and fetal development. The findings reinforce the importance of maintaining maternal oral health to ensure the general health of the offspring, especially in cases where diabetes is present.
