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

Background: This study aimed to develop a nomogram, a visual prediction model to predict the risk of postoperative pneumonia (POP) in elderly patients after hip fracture surgery. Methods: A retrospective analysis was conducted on 711 patients aged 65 and over who underwent surgery for hip fractures. A logistic regression analysis with a nomogram was used to identify independent risk factors for POP. Results: Out of the studied patients, 26 (3.7%) developed POP after surgery. Independent risk factors for POP included age, gender, body mass index (BMI), serum albumin levels, change in inflow E and mitral e' annular velocities (E/e'), severity of fracture (fractured) and administration of diuretics. The results of both univariate and multivariate logistic regression analyses revealed that age, gender, serum albumin levels and diuretics showed significant increase in odds ratio, whereas no significant differences were found in BMI, E/e' and fractured in odds ratios in POP patients. The area under the curve (AUC) of the nomogram model was 0.838, indicating discriminative ability. Conclusions: The nomogram developed in this study predicted the risk of POP in elderly patients with hip fractures. Using this model in clinical practice could allow for appropriate preventive measures to be taken for high-risk patients, potentially reducing the incidence of POP and improving patient outcomes.
