Cyclooxygenase 2 Inhibitors for Headache After Elective Cranial Neurosurgery: Results from a Systematic Review of Efficacy of Cyclooxygenase 2 Inhibitors for Headache After Acute Brain Injury.
Synthesis in Neurocritical care, 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
Headache management after acute brain injury (ABI) is challenging. Although opioids are commonly used, selective cyclooxygenase 2 inhibitors (COXIBs) may be promising alternatives. However, concerns about cardiovascular effects and bleeding risk have limited their use. We aimed at summarizing available data on efficacy of COXIBs for headache management following ABI. A systematic review was conducted through MEDLINE and Embase for articles published through September 2023 (PROSPERO identifier: CRD42022320453). No language filters were applied to the initial searches. Interventional or observational studies and systematic reviews assessing efficacy of COXIBs for headache in adults with ABI were eligible. Article selection was performed by two independent reviewers using DistillerSR. Descriptive statistics were used for data analysis, and meta-analysis was unfeasible because of study heterogeneity. Of 3190 articles identified, 6 studies met inclusion criteria: 4 randomized controlled trials and 2 retrospective cohort studies, all conducted in elective cranial neurosurgical patients (total N = 738) between 2006 and 2022. Five studies used COXIBs in the intervention group only. Of the six studies, four found a reduction in overall pain scores in the intervention group, whereas one showed improvement only at 6 h postoperatively, and one did not find significant differences. Pain scores decreased between 4 and 15%, the largest shift being from moderate to mild severity. Three studies found an overall opioid use reduction throughout hospitalization in the intervention group, whereas one reported a reduction at 12 h postoperatively only. Opioid consumption decreased between 9 and 90%. Two studies found a decrease in hospital length of stay by ~ 1 day in the intervention group. The one study reporting postoperative hemorrhage found a statistically nonsignificant 3% reduction in the intervention group. COXIBs may serve as opioid-sparing adjunctive analgesics for headache control after elective cranial surgery. Limited or no literature exists for other forms of ABI, and additional safety data remain to be elucidated.
