Induced Hypothermia in Patients with Cardiac Arrest and a Non-shockable Rhythm: Meta-analysis and Trial Sequential Analysis.
Synthesis in Neurocritical care, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundControversy surrounds utilization of induced hypothermia (IHT) in comatose cardiac arrest (CA) survivors with a non-shockable rhythm.
methodsWe conducted a meta-analysis and trial sequential analysis (TSA) comparing IHT with no IHT approaches in patients with CA and a non-shockable rhythm. The primary outcome of interest was favorable neurological outcomes (FNO) defined using the Cerebral Performance Category (CPC) score of 1 or 2. Secondary endpoints were survival at discharge and survival beyond 90 days.
resultsA total of 9 studies with 10,386 patients were included. There was no difference between both groups in terms of FNO (13% vs. 13%, RR 1.34, 95% CI 0.96-1.89, p = 0.09, I
conclusionIn this meta-analysis of 9 studies, the utilization of IHT was not associated with a survival benefit at discharge. Although the meta-analysis showed lack of benefit of IHT in terms of FNO and survivals beyond 90 days, the corresponding TSA showed high probability of type-II statistical error, and therefore more randomized controlled trials powered for these outcomes are needed.
