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

backgroundAcute intracerebral haemorrhage (ICH) is devastating with a 1 month mortality rate of ~40%. Cerebral oedema can complicate acute ICH and is associated with poor outcome. In patients with large ICH, the accompanying swelling increases mass effect and causes brain herniation. Mannitol, an osmotic diuretic, is used to treat cerebral oedema after traumatic brain injury, but its safety and efficacy in ICH is unclear. We aim to assess the feasibility of a phase II randomised, controlled trial of mannitol in patients with ICH with, or at risk of, cerebral oedema to inform a definitive trial.

methodsThe mannitol for cerebral oedema after acute intracerebral haemorrhage trial (MACE-ICH) aims to include 45 ICH participants from 10 UK sites with estimated largest diameter of haematoma volume >2 cm, presenting within 72 hours of onset with, or at risk of, cerebral oedema (limited Glasgow Coma Scale (GCS)<9, including motor and visual components only, and National Institutes of Health Stroke Scale>8) with or without mass effect. Participants will be randomised (1:1:1) to 1 g/kg 10% single-dose intravenous mannitol, 1 g/kg 10% mannitol followed by a second dose at 24 hours, or standard care alone. Outcome assessors will be masked to treatment allocation. Feasibility outcomes include proportion of patients approached being randomised, participants receiving allocated treatment, recruitment rate, treatment adherence and follow-up. Secondary outcomes include serum electrolytes and osmolality at days 1-2; change in ICH and oedema volume at day 5; number of participants who developed urinary tract infection, GCS and National Institutes of Health Stroke Scale at day 5±2; length of hospital stay, discharge destination and death up to day 28; death and death or dependency by day 180 and disability (Barthel Index), quality of life (EuroQol, 5-D) and cognition (telephone mini-mental state examination) at day 180. ETHICS AND DISSEMINATION: MACE-ICH received ethics approval from the East Midlands-Leicester Central research ethics committee (22/EM/0242). The trial is funded by a National Institute for Health and Care Research RfPB grant (203080). The results will be published in an academic journal and disseminated through academic conferences and patient support groups. Reporting will be in line with Consolidated Standards of Reporting Trials recommendations. TRIAL REGISTRATION NUMBERS: ISRCTN15383301; EUDRACT 2022-000283-22.
