Long-term social isolation increases visceral pain in rats.
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Long-term social isolation can alter the sensitivity to somatic pain, however, its impact on visceral pain sensitivity remains unknown. The purpose of this study is to investigate the effect of long-term social isolation on visceral pain sensitivity in rats. 4-week social isolation rearing significantly increased CRD-induced AWR score and decreased pain threshold as compared to group rearing. There was no significant difference in the number of spontaneous visceral pain behaviors between group and isolation rearing rats. The number of fecal bolus produced by isolation rearing rats was comparable to that produced by group rearing rats. Consistent with 4-week isolation, CRD-induced AWR score in 8-week isolation rearing rats was higher than that in group rearing rats. While, pain threshold was lower in 8-week isolation rearing rats than in group rearing rats. There was no significant difference in the number of spontaneous visceral pain behaviors and fecal bolus between 8-week isolation and group rearing rats. There results indicated that long-term social isolation induces visceral hypersensitivity in rats, but this effect is unrelated to an increase in stress levels.
