Effects of Substance P for Liver Regeneration in Rat Hepatectomy Models: A Preliminary Experimental Animal Study.
Article in Annals of transplantation, 2022. 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
BACKGROUND This experiment was designed to investigate the effect of substance P (SP) on liver regeneration after partial hepatectomy in a rat model. MATERIAL AND METHODS Male Sprague-Dawley rats were used in this experiment and were divided into an untreated sham group (n=3); a saline group (control group) given a saline injection after hepatectomy (n=4); and an SP group (experimental group) given SP injection after hepatectomy (n=4). The experiments were repeated 3 times in the sham, saline, and SP groups (days 1, 2, and 3). Liver function tests were performed on the serum. Immunohistochemistry was performed for proliferating cell nuclear antigen (PCNA), Ki-67, and CD133, and western blotting was performed for PI3KC, Akt, p38, ERK, and mTOR. RESULTS Liver function test results indicated higher levels in the saline group than in the SP group at day 1. However, the difference gradually disappeared at days 2 and 3. PCNA and Ki-67 were more highly expressed in the SP group than in the saline and sham groups at day 1. CD133 was strongly expressed in the SP group at day 2 compared to that in the sham and saline groups. The changes in mTOR/Akt/PI3KC pathway protein and ERK/p38 signaling protein expression levels were not significantly different among groups. CONCLUSIONS SP accelerated the regeneration stage after hepatectomy in a rat model.
