Incidence of isolated dipstick hematuria and its association with the glomerular filtration rate: a cross-sectional study from the Korean National Health and Nutrition Examination Survey V (2010-2012).

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
purposeTo investigate the incidence of isolated hematuria and its relationship to the glomerular filtration rate (GFR).
methodsData from the Korean National Health and Nutrition Examination Survey V were used. A stratified, three-stage, clustered probability design was used to collect representative data on the Korean population. Ultimately, 18,587 participants were included. The incidence of isolated dipstick hematuria and its relationship with the GFR (estimated by the Chronic Kidney Disease Epidemiology Collaboration equation) were evaluated.
resultsThe analysis showed that 31.8% of the population had isolated hematuria, the incidence of which significantly increased with age (P trend < 0.001). As the severity of hematuria increased, the ratio of GFR < 60 ml/min/1.73 m(2) and 60 ml/min/1.73 m(2) ≤ GFR < 90 ml/min/1.73 m(2) was significantly increased (P trend < 0.001). After adjusting for the confounders, the mean GFR of the grade 3+ (grades 3, 4, 5) hematuria group was significantly reduced compared to that of the negative, grade 1, and grade 2 hematuria groups (with an adjusted mean ± standard error of 94.0 ± 0.8 vs. 97.2 ± 0.3 ml/min/1.73 m(2), P < 0.001). Additionally, the odds ratio of the grade 3+ hematuria group for a GFR < 60 ml/min/1.73 m(2) was significantly increased compared to that of the negative, grade 1, and grade 2 hematuria groups after adjusting for the confounders (adjusted odds ratio 1.468, 95% confidence interval 1.049-2.054, P = 0.025).
conclusionAn effective health policy for hematuria screening is needed for older age groups. A strategy of careful checkups and counseling regarding renal function is necessary for patients with isolated hematuria.
