Prognostic value of combining nutritional inflammatory index trajectories and tumor characteristics in cervical cancer.
Article in BMC women's health, 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
objectiveThis investigation seeks to examine how varying longitudinal patterns in nutritional inflammatory index (NII) correlate with clinical outcomes in cervical cancer patients, while developing predictive models for prognosis.
methodsWe retrospectively analyzed 502 surgically treated cervical cancer cases, incorporating comprehensive clinical parameters, laboratory measurements, and longitudinal follow-up data. Three NII components-advanced lung cancer inflammation index (ALI), neutrophil-albumin ratio (NAR), and prognostic nutritional index (PNI)-were evaluated for their temporal dynamics and relationships with overall survival (OS) and progression-free survival (PFS). Machine learning techniques identified critical predictors for constructing nomograms estimating 3-, 5-, and 10-year survival probabilities.
resultsPatients maintaining consistently low ALI/PNI values or elevated NAR levels demonstrated significantly poorer outcomes, manifesting earlier disease progression or mortality (log-rank p < 0.001). Based on the key variables screened by the machine learning algorithm, the OS model integrates variables such as NII (PNI), tumor characteristics (federation of gynecology and obstetrics (FIGO) grade, tumor size, lymph node metastasis, cancer antigen 125 (CA125), squamous cell carcinoma (SCC_Ag)), and surgical intervention, while the PFS model incorporates multi-dimensional factors such as PNI, FIGO stage, tumor size, lymph node metastasis, diabetes, surgery, and targeted therapy. Predictive accuracy remained robust across timepoints, with OS model AUCs of 0.894 (95%CI:0.853-0.934), 0.917 (0.88-0.954), and 0.925 (0.883-0.967) for 3-, 5-, and 10-year predictions respectively. Corresponding PFS model AUCs were 0.903 (0.868-0.938), 0.902 (0.865-0.939), and 0.905 (0.862-0.948).
conclusionThis study identifies that sustained low ALI/PNI or elevated NAR levels are strongly associated with adverse clinical outcomes in cervical cancer, including earlier progression and mortality.
