1 · What the graph read from it

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.

2 · The registry

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: To develop and rigorously validate a multivariable prediction model for postoperative pneumonia (POP) in elderly patients with hip fracture by integrating the five-item modified frailty index (5‑mFI), the Geriatric Nutritional Risk Index (GNRI), and various clinical variables, with comprehensive assessment of model performance. Methods: We conducted a retrospective cohort study of 2183 patients aged ≥65 years undergoing hip fracture surgery. Predictors included comorbidities, laboratory values (including partial pressure of oxygen [PO Results: The extended logistic regression model identified chronic obstructive pulmonary disease (odds ratio [OR]=2.60), postoperative intensive care unit admission (OR=2.72), lower PO Conclusion: We developed and internally validated a robust prediction model for POP that integrates frailty, nutrition, and key clinical variables. The model demonstrates strong, validated performance and clinical utility, providing a practical tool for preoperative risk stratification to guide targeted preventive measures in elderly patients with hip fracture.
