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: Postoperative acute kidney injury (AKI) is a common and serious complication following hip fracture surgery in older adults. This study aimed to identify predictors of postoperative AKI and evaluate its association with short-term complications after extracapsular hip fracture surgery. Methods: A retrospective cohort study was conducted using TriNetX Analytics, a federated electronic health record network of 109 United States healthcare organizations (2015-2025). Adults aged ≥ 65 years undergoing extracapsular hip fracture surgery (CPT 27244/27245) were included; those with prior AKI (ICD-10-CM N17) were excluded. Propensity score matching was performed 1:1. Predictors were assessed using Cox proportional hazards modeling and postoperative complications were compared using risk ratios, odds ratios, and Kaplan-Meier survival analysis. Results: Among 46,287 eligible patients, 1,413 matched pairs (n=2,826) were analyzed. Predictors of postoperative AKI included Black race (HR=1.64), White race (HR=1.21), elevated preoperative serum chloride (HR=1.04), bicarbonate (HR=1.03), creatinine (HR=1.18), and decreased serum protein (HR=1.11). Protective factors included Hispanic/Latino ethnicity (HR=0.70), preoperative opioid use (HR=0.58), elevated serum sodium (HR=0.97), and Tdap vaccination (HR=0.82). Postoperative AKI was associated with increased 30-day risk of myocardial infarction (RR=8.01), sepsis (RR=5.99), respiratory failure (RR=5.30), arrhythmia (RR=2.22), deep vein thrombosis (RR=1.98), transfusion (RR=1.92), and mortality (RR=2.22). Conclusions: Postoperative AKI was independently associated with increased short-term morbidity and mortality following extracapsular hip fracture surgery in older adults. Recognition of perioperative risk factors may support earlier identification and targeted strategies to reduce AKI incidence and improve postoperative outcomes.
