Admission prognostic nutritional index predicts prolonged hospitalization in severe odontogenic deep neck infections.
Article in Odontology, 2026. 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
objectivesSevere odontogenic deep neck infections (DNIs) can be life threatening. This study investigated the nutritional status of affected patients and evaluated the usefulness of the Prognostic Nutritional Index (PNI) at admission in helping maxillofacial surgeons identify, at presentation, those likely to require extended hospitalization.
methodsA total of 112 patients treated for odontogenic deep neck abscesses and necrotizing soft tissue infections at five hospitals in Japan. Patients were included. Patients were categorized by length of hospitalization duration and factors associated with prolonged hospitalization were analyzed using propensity score matching to minimize bias. Spearman's rank correlation analysis was also performed to assess the relationship between PNI and hospitalization duration.
resultsFifty patients (44.6%) required hospitalization for more than 14 days. Multivariate analysis identified PNI ≤ 41.2 (odds ratio [OR] = 2.79) and the presence of abscesses in multiple deep neck spaces (OR = 2.76) as significant predictors of prolonged hospitalization. Propensity score analysis confirmed the significant association between PNI and length of hospitalization duration (P = 0.048). In addition, Spearman's rank correlation coefficient was r = - 0.471 (P < 0.001), indicating a moderate negative correlation.
conclusionThe admission PNI may serve as a useful adjunctive indicator for predicting prolonged hospitalization in patients with severe odontogenic DNIs, as it reflects both nutritional status and systemic inflammation.
