The utility of urinary liver-binding fatty acid protein levels as a promising biomarker for early detection of acute kidney injury following coronary angiography: a pre-post study at Suez Canal University Hospital.

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
backgroundContrast-induced acute kidney injury (CI-AKI) is a common complication of coronary angiography and percutaneous coronary interventions, with incidence rates ranging from 1% to 25%. Pre-existing renal impairment is the most significant predisposing factor. L-FABP has been evaluated as a biomarker for CIN. THE AIM OF THIS STUDY: The aim of this study was early detection of acute kidney injury after coronary angiography by detecting levels of L-FABP as a biomarker to improve the patient’s outcome.
methodsThis is a Pre-post study, as we assessed urinary levels of L-FABP and serum creatinine before and after IV contrast. Sixty-two patients (42 males and 20 females) were recruited from the cardiac catheterization unit of Suez Canal University Hospitals in Ismailia City between December 2021 and January 2022. The study involved medical history, clinical examinations, blood samples for lipid, CBC, creatinine, HbA1C for diabetics, urine L-FABP measurement, and echocardiography. The Mehran score was calculated for each patient to predict risk for CIN and dialysis. Follow-up care for individuals diagnosed with CIN until recovery.
resultsNearly 70% had hypertension (HTN), 48.4% were diabetic, and 16% had CKD. The mean urinary L-FABP pre-contrast was 187.13 ± 59.07 ng/l, and post-contrast was 201.79 ± 81.8 ng/l. The incidence of CIN was 9.7%. urinary L-FABP levels showed a statistically significant difference within the first 6 h and after 48 h of contrast injection.
conclusionIn conclusion, CIN is prevalent in advanced-age patients with higher HbA1c levels in patients undergoing coronary interventions. Post-contrast levels showed a significant difference, suggesting potential for early renal injury detection.
