The impact of body composition and systemic inflammatory markers on postoperative complications in early-stage cervical cancer.
Article in Frontiers in oncology, 2025. 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
Objective: Patients with cancer often present with alterations in body composition and systemic inflammation. Guided by this observation, we sought to determine whether these factors are associated with postoperative complications in early-stage cervical cancer. Methods: In this retrospective cohort study, we analyzed data from 223 patients with early-stage cervical cancer treated at our center between July 2018 and December 2021.Postoperative complications were graded using the Clavien-Dindo classification. Systemic inflammatory markers were calculated from hematological parameters, while body composition indices were derived from computed tomography (CT) images at the third lumbar vertebra (L3) level and patient's height. Group comparisons were performed using the χ² test, independent samples t-test, or Mann-Whitney U test, as appropriate. Binary logistic regression was applied to identify independent predictors of complications and conduct to sensitivity analysis to verify the robustness of the model. Results: Preoperative CT scans and hematological tests were performed a mean of 3.4 and 4.1 days before surgery, respectively. Postoperative complications were predominantly Grade 1 (n=124, 55.6%), followed by Grade 2 (n=69, 30.9%) and Grade 3 (n=30, 13.5%). No complications ≥ Grade 4 were observed. Patients with complications ≥ Grade 2 were more likely to undergo open surgery, present with larger tumors, exhibit lower skeletal muscle index (SMI) and prognostic nutritional index (PNI), higher visceral adipose tissue index (VATI), as well as greater intraoperative blood loss, lower preoperative and postoperative albumin levels, increased thrombotic risk, and longer hospital stays. Multivariate analysis identified that a higher complication grade (≥Grade 2) was significantly associated with low SMI (OR = 0.34, 95% CI = 0.18-0.64, P < 0.001), high VATI (OR = 1.04, 95% CI = 1.02-1.06, P < 0.001), and low PNI (OR = 0.91, 95% CI = 0.84-0.98, P = 0.008). No significant associations were found with IMATI, SATI, or systemic inflammatory markers (NLR, PLR, LMR, NPR, SII). After conducting sensitivity analyses on the key findings, the results remained robust. Conclusion: Sarcopenia, visceral adiposity, and low PNI are independently associated with a higher risk of clinically significant postoperative complications in patients with early-stage cervical cancer.
