Cardiovascular Volume Reserve in Patients with Heart Failure and Reduced Ejection Fraction.
Observational study in Journal of cardiovascular translational research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This study aimed to investigate the relationship between intravascular volume and intracardiac filling pressures in stable HF patients with reduced ejection fraction (HFrEF). A total of 40 HFrEF patients (LVEF 36 ± 10%) (10 subjects with a pulmonary artery catheter) underwent intravascular volume expansion with 1 L hydroxyl-ethyl-starch over 3 h with coinciding intravascular volume measurements (technetium (99 tc)-labeled red blood cell technique). Intravascular blood volume increased from 5.0 ± 1.0 L to 5.7 ± 1.0 L (p < 0.0001). No change in clinical status, echocardiographic indices, or cardiac filling pressures was noticed. Invasively measured right atrial pressure and pulmonary arterial wedge pressure increased significantly immediately after start of infusion (4 ± 2 mmHg to 8 ± 4 mmHg; p = 0.01 and 10 ± 3 mmHg to 15 ± 6 mmHg; p = 0.01, respectively), decreased afterwards, and remained stable for 3 h (6 ± 2 mmHg and 14 ± 4 mmHg, respectively). The accuracy of cardiac filling pressure estimates to predict intravascular volume expansion was low (all AUC < 0.65).
