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
The likelihood of neurological recovery after out-of-hospital cardiac arrest (OHCA) may be influenced by advanced age. This study aims to evaluate the impact of advanced age on neurological recovery in elderly OHCA survivors treated with targeted temperature management (TTM). This retrospective observational study, using a nationwide population-based OHCA registry, was conducted from January 2016 to December 2020. Non-traumatic elderly (≥ 65 years) comatose OHCA survivors treated with TTM were categorized according to age (65-69, 70-74, 75-79, and ≥ 80 years). Among 23,336 admitted OHCA patients, 3,398 were treated with TTM. Excluding 2,033 non-elderly patients, 1,365 were analyzed. Among the four groups, the rate of good neurological outcomes decreased by advanced age (24.2%, 16.1%, 11.4%, and 5.9%, respectively), which was also observed after subgroup analysis based on the initial shockable (40.6%, 31.5%, 28.6%, and 14.9%, respectively) and non-shockable rhythm (10.6%, 7.2%, 4.1%, and 3.4%, respectively). Multivariate analysis showed the adjusted odds ratio (aOR) for good neurological outcome decreased as age increased (65-69: reference, 70-74: aOR 0.70, 75-79: aOR 0.49, and ≥ 80 years: aOR 0.25). The optimal age cutoffs for good outcomes in elderly OHCA survivors with shockable and non-shockable rhythm were 77 and 72 years, respectively. The neurologic recovery rate in OHCA survivors treated with TTM gradually decreased with increasing age. However, even patients aged ≥ 80 years with shockable rhythm had a good neurologic outcome of 14.9% compared with patients aged 65-69 years with non-shockable rhythm (10.6%).
