Age-related tolerability of hard-channel puncture and drainage for chronic subdural hematoma: A single-center retrospective study.
Observational study in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Chronic subdural hematoma predominantly occurs in the elderly population; however, this study includes patients across all age groups. Age was analyzed as a continuous variable to evaluate its effect on the tolerability of hard-channel therapy in elderly patients. We retrospectively analyzed 191 chronic subdural hematoma patients treated with hard-channel therapy from December 2016 to March 2023. Age was treated as a continuous variable to assess its association with mortality, surgery-related complications, recurrence, functional outcomes, and hospital stay length. This study aimed to assess the age-related tolerability of hard-channel therapy for chronic subdural hematoma, focusing particularly on elderly patients. Among 191 patients with chronic subdural hematoma treated by hard-channel therapy, the median age was 75 years. Age was significantly associated with increased mortality (odds ratio 1.14, P = .020) and poorer functional recovery measured by mRS (β = 0.02, P = .009). No significant associations were found between age and complication rates, recurrence, or hospital stay duration. Preoperative Barthel Index independently predicted mortality risk after adjustment. Comorbidity burden was correlated with worse functional outcomes. Age was significantly associated with adverse postoperative outcomes in univariate analysis, but this effect was attenuated after adjustment for functional status and comorbidities. This suggests age mainly reflects cumulative comorbidity and functional impairment. Incorporating these factors into risk models is essential for evaluating elderly patients undergoing hard-channel therapy.
