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

backgroundPulmonary hypertension (PH) is a well-recognized complication of left ventricular heart failure (HF). HYPOTHESIS: Differences exist in demographic, clinical, hemodynamic, and survival characteristics of patients with left ventricular HF who have combined postcapillary and precapillary PH (CpcPH), isolated postcapillary PH, or no PH.

methodsA secondary data analysis was conducted using a large prospective database of patients undergoing right heart catheterization from 1994 to 2012. One-year mortality postcatheterization was assessed between PH groups using Kaplan-Meier and log-rank techniques, as well as a multivariate Cox proportional hazards model adjusted for age, sex, diabetes, chronic kidney disease, atrial fibrillation, and chronic obstructive pulmonary disease. Mortality rates were calculated for each group as deaths per 100 person-years.

resultsOf the 724 patients identified, 29.4% (n = 213) had no evidence of PH, 63.1% (n = 457) had isolated postcapillary PH, and 7.5% (n = 54) had CpcPH. Compared with no PH, there was an increased mortality rate within 1 year for CpcPH patients (crude hazard ratio: 5.22, 95% confidence interval: 2.06-13.22), but not for isolated postcapillary PH patients (crude hazard ratio: 2.12, 95% confidence interval: 0.99-4.57). Adjusted analyses revealed similar results. Mortality rates per 100 person-years were 3.9, 8.4, and 21.0 for no PH, isolated postcapillary PH, and CpcPH patients, respectively.

conclusionsHeart failure patients with CpcPH are associated with increased death rate 1 year post-cardiac catheterization, compared with patients without PH. They are a high-risk PH group and should be evaluated and diagnosed earlier in the disease state.
