1 · What the graph read from 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.

2 · The registry

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

backgroundDecreased lean body mass or muscle mass is associated with decreased bone mineral density in individuals with preserved renal function. However, the association between muscle mass and bone mineral density in chronic kidney disease (CKD) patients is not well known. The aim of this study was to assess the relationship between muscle mass estimated from urine creatinine (UCr) and bone mineral density in Korean CKD patients.

methodsThis cross-sectional study analyzed 1872 participants from the Korean Cohort Study for Outcome in Patients With Chronic Kidney Disease (KNOW-CKD) cohort. Participants underwent UCr (g/day) and bone mineral density measurements, which were measured at the lumbar spine, total hip, and femoral neck by dual-energy X-ray absorptiometry. Patients were divided into three groups according to the tertiles of 24 h UCr (T1-T3).

resultsThe mean values for 24 h urine creatinine of T1, T2, and T3 were 0.83 ± 0.23 g, 1.18 ± 0.24 g, and 1.55 ± 0.38 g, respectively. A total of 172 patients were diagnosed with osteoporosis. The number of patients in each group was 92 (14.4%) in T1, 45 (7.3%) in T2, and 35 (5.7%) in T3. The odds ratio (95% confidence interval) for osteoporosis was 0.37 (0.20-0.69) for 1 g/day increase of UCr. Compared with T1, the odds ratios (95% confidence interval) for osteoporosis were 0.58 (0.39-0.87) for T2 and 0.51 (0.32-0.80) for T3.

conclusionLow 24-h UCr was associated with low bone mineral density. Low 24 h UCr was significantly and independently associated with osteoporosis in Korean pre-dialysis CKD patients. Further research is warranted to verify the influence of muscle mass on bone health in CKD.
