Patient-reported headache before and after surgery for pituitary adenomas: a longitudinal single-centre study.
Article in Acta neurochirurgica, 2026. 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
introductionTo what extent pituitary adenomas cause headache is controversial and the impact of transsphenoidal surgery on headache remains uncertain.
methodsWe conducted a prospective, single-centre study of patients undergoing surgery for pituitary adenomas between 2014 and 2024. Headache was assessed using the EORTC QLQ-BN20 module, question four, at baseline, one month, and six months postoperatively. Demographic, clinical, and surgical data were analysed for associations with headache outcomes.
resultsOf 207 eligible patients, 134 completed all assessments (63% male; median age 55 years). Preoperatively, 50% reported no headache, 33% a little, 8% quite a bit, and 9% very much headache. Headache was more common in females, but there was no relation to tumour related factors. At one month, 31% improved, 52% remained unchanged, and 16% worsened. At six months, 34% improved, 56% remained unchanged, and had 10% worsened compared to preoperatively. Among patients with preoperative headache (n = 67), 52% reported improvement at one month and 55% at six months. Among patients with no headache preoperatively, 25% and 12% reported having headache at one and six months, respectively. No demographic, tumour-related, or perioperative variables were significantly associated with headache change.
conclusionIn this prospective longitudinal study, approximately half of patients with preoperative headache reported improvement following pituitary surgery, while a minority experienced worsening. No clear clinical predictors of headache before surgery or outcome after surgery were identified, suggesting a multifactorial nature of headache in patients with pituitary adenomas.
