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

backgroundDespite optimized medical therapy, severe idiopathic pulmonary arterial hypertension (IPAH) is a devastating disease with a poor outcome. Autoantibodies have been detected in IPAH that can contribute to worsening of the disease.

objectivesThe objective of this prospective, open-label, single-arm, multicenter trial was to evaluate the safety and efficacy of immunoadsorption (IA) as an add-on to optimized medical treatment for patients with IPAH.

methodsA total of 10 IPAH patients received IA over 5 days. Their clinical parameters, including hemodynamics measured by right heart catheter, were assessed at baseline and after 3 and 6 months. The primary endpoint was the change in pulmonary vascular resistance (PVR). Secondary endpoints included the change in 6-min walking distance, quality of life, safety, and plasma levels of IgG and autoantibodies.

resultsThe evaluation of the 10 IPAH patients (75% female; 51 ± 12 years; 166 ± 10 cm; WHO functional class III; 53% on combination therapy) revealed that IA was a safe procedure that efficiently removed IgG and autoantibodies from the circulation. After 3 months, the mean PVR improved significantly by 13.2% (p = 0.03) and the cardiac index improved by 13.1%, but no significant changes were found in 6-min walking distance. The quality of life physical functioning subscale score significantly improved after 6 months. The serious adverse events in 3 patients were possibly related to IA and included pneumonia, temporary disturbance in attention, and thrombocytopenia.

conclusionsIA as an add-on to targeted medical treatment for IPAH is a safe procedure with beneficial effects on hemodynamics, especially in patients with high levels of autoantibodies. Larger-scale controlled studies are needed to assess its efficacy in IPAH and to identify responders.
