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

objectiveIn patients with heart failure (HF), Cheyne-Stokes respiration (CSR) is characterized by chronic hyperventilation (HV) with low arterial partial pressure of carbon dioxide (pCO2). It is still unclear whether this HV represents a compensatory response to HF or an independent comorbidity. This study investigated the hemodynamic effects of HV in HF patients and volunteers.

methodsA total of 15 volunteers [13 male, 25 ± 4 years, brain natriuretic peptide (BNP) <49 pg/mL, left ventricular rejection fraction (LVEF) >55 %) and 20 HF patients with reduced LVEF (15 male, 67.7 ± 12 years, NYHA class 2.6 ± 0.6, BNP 790 ± 818 pg/mL, LVEF 32.4 ± 7.3 %) were enrolled. Hemodynamics was monitored noninvasively in volunteers (TaskForce Monitor, CNSystems) and invasively in HF patients.

resultsDuring HV, the transcutaneous CO2 pressure in volunteers decreased from 38.7 ± 2.5 to 28.6 ± 3.3 mmHg (p < 0.001) and pCO2 in HF patients decreased from 33.6 ± 3.7 to 22.2 ± 3.2 mmHg (p < 0.001). There was a significant increase in cardiac output (CO) in both volunteers (6.2 ± 1.3-7.5 ± 1.3 L/min, p < 0.001) and HF patients (4.4 ± 1.3-5.0 ± 1.3 L/min), mainly as a result of an increase in heart rate (67.4 ± 7.6-82.8 ± 10.9/min, p < 0.001; and 77.2 ± 17.7-86.2 ± 22.4/min, p < 0.001, respectively); stroke volume (SV) was unchanged in volunteers (93.7 ± 19.6-93.8 ± 21.4 mL) and only slightly increased in HF patients (64.4 ± 28.7-68.5 ± 23.2 mL).

conclusionsCSR with associated HV may be a compensatory mechanism in patients with a failing heart. This compensatory mechanism includes an increase in heart rate, which might be deleterious in the long run.
