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

Intravenous diuretics are the cornerstone of management for patients hospitalized for heart failure. Physiologic data suggest that intermittent high-dose furosemide promotes neurohormonal activation, which a slow continuous infusion might remediate. However, the limited clinical data comparing dosing schemes are confounded. This study was a randomized, open-label, single-center trial of twice-daily bolus injection versus continuous infusion furosemide in patients hospitalized with heart failure and volume overload. The primary outcome was change in creatinine from admission to hospital day 3 or discharge. Twenty-one patients were randomized to bolus injection and 20 patients to continuous infusion. Baseline characteristics were balanced between study arms except for gender, with a mean age of 60 +/- 15 years, a mean ejection fraction of 35 +/- 19%, and a mean creatinine level of 1.9 +/- 1.2 mg/dl. The mean doses of furosemide were similar between arms over the first 48 hours (162 +/- 48 and 162 +/- 52 mg/24 hours). None of the outcomes differed significantly between bolus and continuous dosing from admission to hospital day 3 or discharge (mean change in creatinine -0.02 vs 0.13 mg/dl, p = 0.18; urine output 5,113 vs 4,894 ml, p = 0.78; length of stay 8.8 vs 9.9 days, p = 0.69). All patients survived to discharge. In conclusion, there were no substantial differences between bolus injection and continuous infusion of equal doses of furosemide for the treatment of patients hospitalized with heart failure. Given the high prevalence of heart failure hospitalization and the disparate results of small studies regarding optimal dosing of loop diuretics to treat these patients, larger multicenter blinded studies are needed.
