Augmentation of ECG QRS complexes after fluid removal via a mechanical ultrafiltration pump in patients with congestive heart failure.
Article in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundAugmentation of the amplitude of ECG QRS complexes, correlating with loss of weight or fluid volume removed, has been documented in patients with congestive heart failure (CHF).
methodsWe investigated the effect of an ultrafiltration (UF) pump on the fluid removal and the amplitude of ECG QRS complexes in patients with CHF. Nine patients aged 48.3 +/- 10.4 years with CHF were treated with an UF system, and weights, fluid removed, and sums of the amplitude of QRS complexes (SigmaQRS), were inter-correlated.
resultsUF resulted in removal of 4.62 +/- 1.82 L of fluid, 5.0 +/- 2.9% decrease in the weights (P = 0.002) and 18.1 +/- 16.8% increase in the SigmaQRS (P = 0.012). There was a moderate correlation of % increase in the SigmaQRS and net fluid volume losses (UF + urine - oral intake), (r = 0.67, P = 0.0471, and a poor correlation between % increase in the SigmaQRS and % decrease in weights (r = 0.11, P = 0.77). Correlations of the change in weights after UF with the fluid removed by UF, or with the volume of total fluid loss (including insensible losses) were moderate but barely statistically significant (r = 0.65, P = 0.0559), and (r = 0.65, P = 0.0577), correspondingly.
conclusionAugmentation of the amplitude of QRS complexes correlates well with net fluid loss in response to UF in patients with CHF, and can be employed as an index of effectiveness of therapy. Also, a model of fluid losses in patients treated for CHF is being proposed.
