Effect of glomerular filtration rate and proteinuria on medical cost among screened subjects.
Article in Clinical and experimental nephrology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundChronic kidney disease is a predictor of end-stage renal disease (ESRD) and cardiovascular disease (CVD). Therefore, the medical expenses are higher with the decrease in glomerular filtration rate (GFR). However, few studies have examined the medical expenses according to the baseline GFR.
methodsWe investigated the relationship between GFR at health checks and medical expenses, combining the registries of both the health checks and report of medical expenses (receipts). The health checks were done from April 2008 to March 2009, and the eligible subjects were covered by the Okinawa Branch of the Japan Health Insurance Association. All reports of medical expenses were reviewed from April 2008 to March 2010 (24 months).
resultsA total of 74,354 subjects, 38.2 % females with the mean age of 48.1 years, were examined according to whether they had visited medical facilities during the study period. The total number of receipts was 773,276. The average receipt point, 1 point = 10 Yen, was 686,410 (eGFR < 15), 56,408 (eGFR 15-29), 47,263 (eGFR 30-44), 24,372 (45-59), 16,018 (eGFR 60-74), 13,893 (eGFR 75-89), 13,990 (eGFR 90-104), 14,717 (eGFR 105-119), and 19,139 (eGFR 120 and over), respectively. The relationship between eGFR and medical expense was U-shaped, and the expense was lowest at eGFR 75-89.
conclusionWe demonstrate that the medical expenses increase as eGFR decreases. Subjects with higher eGFR, 120 and over, seemed to have higher medical expenses.
