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

backgroundSerum chloride is an important homeostatic biomarker in left heart failure, with significant prognostic implications. The impact of serum chloride in the long-term survival of patients with pulmonary arterial hypertension (PAH) is unknown. We tested whether serum chloride levels are associated with long-term survival in patients with PAH.

methodsWe included patients with idiopathic or heritable PAH who had a basic metabolic panel performed at the time of their diagnostic right heart catheterization. Laboratory results were recorded both at diagnosis and 6-month follow-up.

resultsWe included 277 patients, mean age 51 ± 18 years and 73% women, of whom 254 had a follow-up electrolyte determination at 6 months. Serum chloride was 102.9 ± 3.9 mM/L at diagnosis. A serum chloride ≤ 100 mM/L was noted in 65 (24%) and 53 (21%) patients at diagnosis and 6 months, respectively. Patients with serum chloride ≤ 100 mM/L at 6 months tracked with increase mortality when adjusted by age, sex, pulmonary vascular resistance, diuretics or prostacyclin analogs usage, and serum creatinine and sodium at 6 months (hazard ratio, 1.83; 95% CI, 1.11-3.00). This group of patients was older, with decreased functional capacity, had worse renal function, took more diuretics, had higher pulmonary artery wedge pressure but lower mean pulmonary artery pressure, transpulmonary gradient, and pulmonary vascular resistance.

conclusionsSerum chloride at 6 months from the PAH diagnosis is a strong and independent predictor of mortality in patients with idiopathic or heritable PAH, even after adjusting serum sodium, renal function, diuretic, and prostacyclin analog usage.
