Examining Referral Pathways for Patients with Hematuria: A Real-World Retrospective Analysis.
Article in Glomerular diseases. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Follow-up for hematuria, often found incidentally on urinalysis, is critical as it may be an early sign of glomerular disease or malignancy. We evaluated nephrology and urology referral patterns for outpatients with hematuria, and factors associated with nephrology and urology referrals. Methods: This retrospective, observational cohort study leveraged electronic health record data from a large, regional health care system in Pennsylvania, USA. Outpatients with hematuria (≥1+ blood) on dipstick urinalysis from January 1, 2022, to September 30, 2022, without nephrology/urology appointments in the prior 10 years or prior genitourinary cancer were enrolled. The primary objective evaluated the proportion of outpatients with hematuria who had nephrology or urology referrals or appointments within 6 months following initial presentation. Secondary objectives evaluated concurrent proteinuria and follow-up testing patterns. Results: The mean (standard deviation) age of the 5,475 outpatients with hematuria on urinalysis was 60.5 (20.8) years, and most were female (78.0%). Overall, 774/5,475 (14.1%) patients with hematuria had a nephrology or urology referral/appointment within 6 months following presentation. Urine microscopy was performed at the time of hematuria detection for 3,324/5,475 (60.7%) patients, of whom 2,388 (71.8%) had ≥3 red blood cells (RBCs) per high-power field (HPF). Repeat urinalysis was performed for 1,582/5,475 (28.9%) patients. Increased referral likelihood was associated with male sex (odds ratio: 2.3; 95% confidence interval [CI]: 1.9-2.7) and ≥30 RBCs/HPF on microscopy (odds ratio: 1.7; 95% CI: 1.3-2.1). Of 4,952 patients with proteinuria data, 2,375 (48.0%) had hematuria and ≥1+ protein on urinalysis, and 373/2,375 (15.7%) had nephrology ( Conclusion: This study provides insight into current outpatient hematuria management patterns. The low referral rates, particularly with concurrent hematuria and proteinuria, highlight opportunities to improve management moving forward.
