Sedation and analgesia in post-cardiac arrest care: a post hoc analysis of the TTM2 trial.
Trial report in Critical care (London, England), 2025. 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
backgroundThe routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening.
methodsThis was a post hoc analysis of the TTM2-trial, which randomized 1900 out-of-hospital cardiac arrest patients to either normothermia or hypothermia. In both groups, deep sedation (Richmond Agitation and Sedation Scale ≤ -4) was mandatory during the 40-h intervention. Cumulative doses of sedatives and analgesic drugs were recorded within the first 72 h from randomization. Outcomes were functional outcome (modified Rankin Scale) and survival status at 6 months, occurrence of clinical seizures during the intensive care stay, and late awakening (Full outline of unresponsiveness motor score of four 96 h after randomization). Cumulative propofol doses were divided into quartiles (Q1-Q4). Logistic regression models were used to assess associations between sedative doses and functional outcome and survival, clinical seizures, and late awakening, adjusting for the severity of illness and other clinical factors influencing sedation.
resultsA total of 1861 patients were analyzed. In a multivariable logistic regression model, higher propofol doses (Q3, 100.7-153.6 mg/kg) were associated with good functional outcome (OR 1.62, 95%CI 1.12-2.34) and (Q2 and Q3, 43.9-153.6 mg/kg) with survival (OR 1.49, 95%CI 1.05-2.12 and OR 1.84, 95%CI 1.27-2.65, respectively). Receiving fentanyl and remifentanil were associated with good functional outcome (OR 1.69, 95%CI 1.27-2.26 and OR 1.50, 95%CI 1.11-2.02) and survival (OR 1.80, 95%CI 1.35-2.40 and OR 1.56, 95%CI 1.16-2.10). Receiving fentanyl (OR 0.64, 95%CI 0.48-0.86) and higher propofol doses (Q2-4 (43.9-669.4 mg/kg) were associated with the occurrence of clinical seizures. The highest quartile of propofol dose (153.7-669.4 mg/kg, OR 3.19, 95%CI 1.91-5.42) was associated with late awakening.
conclusionsIn this study, higher doses of propofol and the use of remifentanil and fentanyl were associated with good functional outcome and survival, occurrence of clinical seizures, and late awakening.
