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

introductionThe decision whether to operate on patients with intracranial tumors is complex and influenced by patient-specific factors, including the preoperative functional status. This work assesses the risks for mortality and complications, and post-operative recovery in functionally dependent patients undergoing microsurgical resection of intracranial tumors.

methodsObservational two-center study, analyzing institutional registry data. Dependency was defined as admission Karnofsky Performance Scale (KPS) of ≤ 50. The primary endpoint was in-hospital mortality. Secondary endpoints were rate and type [Clavien-Dindo grade (CDG)] of complications, as well as postoperative change in KPS until the 3-month follow-up (M3).

resultsOf n = 1951 patients, n = 98 (5.0%) were dependent. Mortality rates were 2.0% for dependent and 0.4% for independent patients (p = 0.018). In univariable analysis, dependent patients were more likely than independent patients to die in hospital (OR 5.49, 95% CI 1.12-26.8, p = 0.035). In a multivariable model, the effect was slightly attenuated (OR 4.75, 95% CI 0.91-24.7, p = 0.064). Dependent patients tended to experience more postoperative complications. They were more likely to suffer from a severe complication (CDG 4 and 5; OR 3.55, 95% CI 1.49-8.46, p = 0.004). In 40.8 and 52.4% of cases, dependent patients regained functional independence at discharge and M3, respectively.

conclusionsIn operated patients with intracranial tumors presenting functionally dependent at admission, the risk for in-hospital mortality and complications is elevated. However, if conducted successfully, surgery may lead to regain of independence in every second patient within 3 months.
