Effects of Oral Frailty Index-8 Score on Complications After Major Orthopaedic Surgery: A Single-Center Retrospective Study.
Article in Journal of oral rehabilitation, 2026. 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
backgroundOral frailty is defined as age-related oral function decline; however, its effect on surgical patients remains unclear.
objectiveThis study aimed to evaluate the effect of oral frailty index-8 (OFI-8) on postoperative complications.
methodsThis retrospective study included patients aged ≥ 65 years who underwent elective total knee arthroplasty, total hip arthroplasty, or spinal surgery under general anaesthesia. Oral frailty was assessed using the OFI-8, with a total score ranging from 0 to 11, and patients with an OFI-8 score ≥ 4 were categorised as positive for oral frailty. The co-primary outcomes were the incidence of postoperative complications, defined as Clavien-Dindo classification (CDC) grade ≥ II complications, and the Comprehensive Complication Index (CCI) score. The association between a positive result for oral frailty and co-primary outcomes was evaluated using multiple logistic or multiple regression analyses adjusted for clinically relevant factors.
resultsOf the 608 patients included in the final analysis, 314 (51.6%) had OFI-8 scores ≥ 4. The overall incidence of complications with CDC grade ≥ II was 15%, with a mean CCI score of 15.6. After adjustment, an OFI-8 score of ≥ 4 was associated with an increased risk of CDC grade ≥ II complications (odds ratio, 1.65; 95% confidence interval, 1.19-2.42, p = 0.01) and an increased CCI (regression coefficients, 1.7; 95% confidence interval, 0.22-3.2, p = 0.02).
conclusionThe study findings suggest that an OFI-8 score of ≥ 4 is associated with the incidence and severity of postoperative complications.
