The accuracy of a continuous volumetric balancing system in pediatric continuous renal replacement therapy.

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
backgroundIn pediatric continuous renal replacement therapy (CRRT) patients, accurate ultrafiltration (UF) measurement is essential, as both over- and under-UF may result in suboptimal outcomes. Traditionally, CRRT has relied on scale-based UF measurements; however, the recent development of a continuous volumetric balancing system has allowed for the advent of scale-less CRRT.
methodsTo assess the accuracy of the volumetric balancing system, we designed a continuously measuring digital scale, which accounted for dialysate use and collected effluent, allowing us to independently measure UF volume and compare it with the machine reported UF volume.
resultsIn four low weight (6.9-16.7 kg) pediatric CRRT patients, we measured the UF volume over 20 separate runs, comprising a total of 318 hours. Over this time, the total measured UF volume was 50,550 mL ± 296 mL, whereas the total reported UF volume was 50,733 mL, a difference of 183 mL ± 296 mL (0.6 ± 0.9 ml/h), or 0.4 ± 0.6%. For each patient, over 48-112 hours per patient, the differences between the total measured and total reported UF volumes ranged from -7.8 ± 1.7 ml/h to +9.7 ± 1.8 ml/h, or -6.0 ± 1.3% to +5.4 ± 1.0%.
conclusionsIn low-weight, pediatric CRRT patients, the scale-less continuous volumetric balancing system delivers accurate ultrafiltration.
