Body mass index and rest myocardial perfusion defect predicts cardiac death in patients with chronic heart failure.

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
Gated single photon emission computed tomography (SPECT) myocardial perfusion imaging has proven to be invaluable not only in assessing myocardial perfusion, but also in providing functional and volumetric information. The aim of this study was to investigate the value of clinical variables and rest gated SPECT myocardial perfusion imaging for predicting cardiac death in patients with chronic heart failure (CHF). Seventy-three consecutive hospitalized patients with CHF (aged 50.7 ± 16.5 years, 60 men and 13 women; 25 ischemic CHF and 48 non-ischemic CHF) and left ventricular ejection fraction on echocardiography <40%, who underwent rest gated SPECT myocardial perfusion imaging, were followed up for this study. Univariate and multivariate analysis of clinical characteristics and gated SPECT parameters for prediction of cardiac death were performed. During the follow-up period (18.6 ± 8.5 months), 14 (19.2%) cardiac deaths occurred. Multivariate Cox analysis showed that body mass index (BMI, 23.3 ± 4.1 kg/m(2), hazard ratio = 0.85, P = 0.025) and summed rest score (SRS, 11.8 ± 11.5, hazard ratio = 1.05, P = 0.021) were predictive for cardiac death. The optimal threshold of BMI was 25 kg/m(2) and patients with BMI < 25 kg/m(2) had lower survival rate (P = 0.013). The optimal threshold of SRS was set as 11 and patients with SRS > 11 had lower survival rate (P = 0.009). Rest gated SPECT myocardial perfusion imaging provides prognostic information in patients with CHF. BMI and SRS are both predictors of cardiac death in patients with CHF.
