Impact of leptin on postoperative peritoneal adhesion formations in colorectal resection.

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
purposePostoperative peritoneal adhesion formation (PAF) is a distressing complication. Leptin, secreted by fat tissues, may be associated with PAF. However, the relationships between PAF and leptin are unclear. This study investigated the impact of leptin on PAF after colorectal tumor resection.
methodsA cecum cauterization mouse model was used to investigate PAF and its association with leptin. Mice adhesion score (AS) was evaluated on day 7 after treatment. The clinical study included patients who underwent elective colorectal resection with temporary ileostomy between April 2021 and December 2024. The AS was evaluated at the time of ileostomy closure. Patients with the highest AS quartile were classified into the high-AS group; clinical factors associated with PAF were examined. An enzyme-linked immunosorbent assay was used to measure human and murine serum leptin concentrations.
resultsThe animal experiment revealed that serum leptin levels on postoperative day 7 were negatively correlated with mice ASs (P = 0.0043, r = -0.6241). In a clinical study, eight patients had a high AS (27.6%). Visceral fat mass and preoperative serum leptin levels were higher in the high-AS group than in the low-AS group. The serum leptin ratio (postoperative value to preoperative value) on postoperative day 7 was lower in the high-AS group. In multivariate analysis, the serum leptin ratio was an independent factor for classifying into the high-AS group.
conclusionsA decrease in postoperative serum leptin levels was associated with severe PAF. Leptin may be a novel key molecule in PAF.
