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

backgroundInjury to renal tubules plays an important role in the development of various renal diseases; however, the prevalence and significance of renal tubular damage in the general population are unclear. To clarify this point, we conducted a community-based study, using urinary β(2)-microglobulin as a marker of tubular damage.

methodsThe subjects studied were 3,444 Japanese over the age of 40 years. The urinary β(2)-microglobulin-creatinine ratio (UBCR) was assessed in morning spot urine samples.

resultsIn this population, the distribution of the UBCR among these subjects was skewed towards higher values and a high UBCR (≥300 μg/g) was identified in 438 (12.7%) subjects. However, overlap with macroalbuminuria and renal insufficiency [estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m(2)] was observed in only 25 (5.7%) and 58 (13.2%) of these subjects, respectively. Multivariate analysis indicated that a high UBCR was positively associated with aging, hypertension, macroalbuminuria and increased urinary sodium excretion. A 5-year longitudinal analysis in 899 subjects indicated a greater decline in eGFR in parallel with the increase in baseline UBCR. After adjustment for possible confounders, a high UBCR was an independent risk factor for rapid decline in eGFR [<-10 mL/min/1.73 m(2); odds ratio 1.79 (95% confidence interval 1.07-2.99), P = 0.026].

conclusionThis study showed that renal tubular damage was common and was an independent risk factor for renal deterioration in the Japanese population. More attention should be paid to occult renal tubular damage in order to prevent end-stage renal disease.
