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

introductionBronchial thermoplasty (BT) is a bronchoscopic procedure that involves the delivery of thermal radiofrequency energy to the bronchial wall for treating severe asthma. It has been suggested that too many radiofrequency activations could induce serious adverse events (SAEs) at an early stage. We aimed to examine the number of radiofrequency activations at each session and early lung function changes from baseline to determine whether these are related to SAEs.

methodsWe retrospectively investigated 13 consecutive patients who underwent three sessions each of BT for severe asthma from February 2015 to January 2016. Lung function tests were performed on the day before and after each BT procedure. Since we compared the number of activations and lung function changes from baseline after each session, a total of 39 sessions were reviewed. The relationship between the number of radiofrequency activations and each lung function change from baseline was also examined by linear regression analysis.

resultsA total of 10 SAEs (4 of pneumonia, 3 of atelectasis, 2 of bronchial asthma exacerbation and 1 of hemoptysis) were observed following the 39 BT sessions. When we compared sessions with and without SAEs, there were no differences in the number of activations (mean ± SD, 71.5 ± 28.6 times in sessions with SAEs; 66.5 ± 25.1 times in sessions without SAEs; p = 0.772) and lung function changes (mean changes in FVC/%FVC/FEV

conclusionsIncrease in the number of radiofrequency activations during BT is related to a decrease in FEV
