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

introductionAcute exacerbations of chronic obstructive pulmonary disease (COPD) increase disease progression and mortality. Smoking influences treatment and health economics. This study examines how smoking status affects medical costs, hospital stays, and outcomes in acute COPD exacerbations.

methodsWe included 658 patients with acute COPD exacerbations, excluding those with asthma, allergic diseases, bronchiectasis, or tuberculosis. Participants were divided into never smokers (n=218) and smokers (n=440). Smokers were further classified as early smokers (age ≤24 years, n=70) or late smokers (age >24 years, n=370), and as current (n=164) or former smokers (n=276). We used Mann-Whitney U tests, chi-squared tests, and univariate logistic regression (p<0.05).

resultsMedian hospital stay was 11 days (IQR: 8-16) for smokers versus 10 days (IQR: 7-15) for never smokers (p=0.179). Median daily cost was 1280.63 versus 1182.01 RMB (1000 Chinese Renminbi about US$151.4, mean exchange rate 2018) (p=0.217). However, total treatment costs were higher for smokers (median=13477.81 [IQR: 9096.81-22651.91] vs 12296.95 RMB [7954.42-20392.61]; Hodges-Lehmann difference: 1068.87 RMB, p=0.045). Medicare (government health insurance program in China) payments were higher (12389.82 [7528.24-20366.10] vs 10216.77 RMB [4691.43-17742.65]; difference: 2349.09 RMB, p<0.001), while out-of-pocket payments were lower for smokers (1005.00 [100.00-2500.00] vs 1527.03 RMB [960.00-4686.97]; difference: -600 RMB, p<0.001). Early smokers had higher costs, longer stays (difference: 1.0 day, p=0.019), higher daily costs (difference: 173.2 RMB, p=0.001), and greater out-of-pocket payments (difference: 328.5 RMB, p=0.008) than late smokers. Current smokers had higher Medicare and total expenditures than former smokers (p=0.011 and p=0.010, respectively).

conclusionsSmoking, especially early smoking, significantly increases the economic burden of acute COPD exacerbations without affecting hospital stay duration.
