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 endarterectomy is the treatment of choice in chronic thromboembolic pulmonary hypertension (CTEPH). Modern pulmonary vasoactive medication (like endothelin receptor antagonists, phosphodiesterase type 5 inhibitors, and prostacyclins) is used in patients with an inoperable disease and improved prognosis. We evaluate mortality and time to clinical worsening (TtCW) in inoperable CTEPH patients during long-term follow-up.

methodsAll 32 patients with inoperable CTEPH were enrolled between June 2002 and January 2009. TtCW was defined as the combination of death, need for intravenous pulmonary arterial hypertension medication, or 15% decrease in 6-minute walk distance (6-MWD) without improvement in functional class. The Cox proportional hazard regression was used to identify predictors.

resultsDuring a mean follow-up of 3.4 years (range = 0.2-10.2 years), 11 patients died (34%). The 1- and 3-year survival rates were 87 and 77%, respectively. Baseline functional class, 6-MWD, mean pulmonary artery pressure, and pulmonary vascular resistance were predictors for survival. Clinical worsening occurred in 16 patients (50%). The 1- and 3-year rates of freedom from clinical worsening were 74 and 60%, respectively. The only predictor for clinical worsening was the baseline 6-MWD.

conclusionDespite the improvement in medical treatment of inoperable CTEPH, the mortality rate is still high, and clinical worsening occurred in a substantial number of patients during a follow-up of more than 3 years.
