Effect of Experimental Gestational Diabetes Mellitus on Mechanical Sensitivity, Capsaicin-Induced Pain Behaviors and Hind Paw Glabrous Skin Innervation of Male and Female Mouse Offspring.
Article in Journal of pain research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeGestational diabetes mellitus (GDM) induces cardiovascular and metabolic disturbances in offspring. However, the effects of GDM in pain processing in offspring and whether male and female offspring are equally affected is not well known. Thus, we determined: i) whether GDM in mice affects offspring hindpaw mechanical sensitivity, capsaicin-induced spontaneous pain-like behaviors, and epidermal nerve fiber density (ENFD); and ii) whether there is sexual dimorphism in these parameters in offspring from GDM dams.
methodsGDM was induced in pregnant ICR mice via i.p. streptozotocin (STZ). Then, glucose levels from dams and offspring were determined. Male and female offspring 2-3 months of age were evaluated for: a) baseline mechanical sensitivity of the hind paw by using von Frey filaments; b) number of flinches and time spent guarding induced by intraplantar capsaicin (0.1%); and c) density of PGP-9.5 and CGRP axons in the epidermis from the hind paw glabrous skin.
resultsPrepartum levels of glucose in STZ-treated dams were significantly increased compared to vehicle-treated dams; however, GDM or vehicle offspring displayed normal and similar blood glucose levels. Male and female GDM offspring showed significantly greater mechanical sensitivity and capsaicin-induced pain behaviors compared to vehicle offspring. Male GDM offspring displayed a slightly more intense nociceptive phenotype in the capsaicin test. PGP-9.5 and CGRP ENFD in hind paw glabrous skin were greater in male and female GDM offspring versus their controls. Sexual dimorphism was generally not observed in GDM offspring in most of the studied parameters.
conclusionThese results suggest GDM induced greater pain-like behaviors in adult offspring regardless of sex along with an increased ENFD of PGP-9.5 and CGRP in the hind paw glabrous skin. We show that GDM peripheral neuropathy differs from diabetic peripheral neuropathy acquired in adulthood and set the foundation to further study this in human babies exposed to GDM.
