Effects of chronic, urea-induced osmotic diuresis on kidney weight and function in rats.

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
To study the effects of chronic osmotic diuresis which were not associated with hyperglycaemia on the rat kidney, osmotic diuresis was induced by i.v. infusion of urea. A 5 mol/l urea solution was continuously infused at a rate of 100 ml.kg-1 x day-1 on the basis of body weight on day 0. Duration of infusion was 2, 6, 10 or 14 days. Control rats received continuously infused Ringer's solution. Urea-treated groups developed osmotic diuresis (urine flow = about 0.04 ml.min-1 x 100 g body weight-1) comparable to that in rats with experimental diabetes mellitus induced by i.v. streptozotocin (55 mg/kg), however urea-induced osmotic diuresis was not associated with blood glucose level increases. Compared with their controls, rats receiving urea for 2-14 days had markedly increased kidney weight. Rats receiving urea for 10 days showed greatest kidney weight increase, 0.565 +/- 0.044 g/100 g body weight (mean +/- SD), representing a 53% increase compared with the control (0.369 +/- 0.034 g/100 g body weight). Kidney weight was associated with increases in kidney protein content. In contrast, none of control kidney weight values differed significantly from day 0 values (= normal rats; 0.387 +/- 0.028 g/100 g body weight). Creatinine clearance values in urea-treated groups were also higher than those in controls. The maximum value, 0.65 +/- 0.17.ml-min-1 x 100 g body weight-1, was recorded in the 14-day group and was significantly higher than the corresponding control value (0.34 +/- 0.07 ml.min-1 x 100 g body weight-1) (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
