Can a structured questionnaire identify patients with reduced renal function?
Article in European radiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
objectivesTo evaluate a structured questionnaire in identifying outpatients with renal dysfunction before MRI or CT in various age groups.
methodsAll patients completed a questionnaire with five risk factors indicating renal dysfunction: renal disease, renal surgery, hypertension, gout and diabetes. Serum creatinine determined by the point-of-care (POC) technique and estimated glomerular filtration (eGFR) rate was calculated using CKD-EPI equation.
resultsA total of 1,467 patients were enrolled. Thirty-four patients (2%) had an eGFR <30 ml/min/1.73 m(2) and 123 (8%) had an eGFR <45 ml/min/1.73 m(2). Among 55% of the 1,467 patients reporting at least one risk factor, 30 (4%) had an eGFR <30 ml/min/1.73 m(2) and 105 (13%) had an eGFR <45 ml/min/1.73 m(2). Among 651 patients not reporting a risk factor, 4 (0.6%) had an eGFR <30 ml/min/1.73 m(2) and 18 (3%) had an eGFR <45 ml/min/1.73 m(2). All four patients were >70 years old, and 12 of the 18 patients were >70 years old.
conclusionThe questionnaire used in patients <70 years old and determination of eGFR in patients >70 years old identified all patients with an eGFR between 30 and 45 ml/min/1.73 m(2) except 0.4%. KEY POINTS: • A questionnaire can adequately identify patients under 70 with renal dysfunction • 8% of patients referred to CT/MRI have an eGFR <45 ml/min/1.73 m (2) • 55% reported risk factors, but renal dysfunction was only found in 13% • Patients over 70 years should have eGFR determined before CT • eGFR determination is not beneficial when stable MRI agents are used.
