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

Background: The discovery of biomarkers in chronic subdural haematomas (CSDH) suggests that inflammation is part of CSDH pathophysiology. It is unknown whether inflammation reflects an independent CSDH driver or haematoma degeneration. This knowledge holds a potential target for anti-inflammatory treatment in patients at risk of CSDH. This study investigated the association of pro- and anti-inflammatory factors with CSDH development. Methods: This cohort study included all individuals in Denmark over 50 years between 2007-2018. The outcome was first-time CSDH surgery. Hazard ratios (HR) according to potential risk factors were estimated using Cox regression, with age as underlying time scale. Results: Among the 2,391,853 individuals, head trauma was registered in 427,612 individuals (17%), and among these, only 812 were operated for CSDH (0.18%). Among individuals without registered head trauma, the pro-inflammatory conditions of alcohol addiction, diabetes, anti-hypertensive treatment, and chronic hepatic disease were significantly associated with CSDH among individuals (50-74 years). The use of glucocorticoids displayed a decreased risk in cohort members aged 75 and older. Non-steroid anti-inflammatory drugs and statins appeared to be risk factors for CSDH in individuals between the ages of 50-64 and 65-74. Conclusion: Although head trauma was a risk factor for CSDH, the absolute risk was low (0.18%), which does not support preventive measures after emergency room contacts for head trauma. Interestingly, pro-and anti-inflammatory factors were significantly associated with CSDH in patients without registered head trauma, and the pronounced age-dependency of the associations suggests that the pathophysiological mechanisms vary with age.
