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
backgroundDue to the improved clinical management of aging population and the consequently declined mortality among patients with critical illnesses, the number of survivors from intensive care units (ICUs) keeps rising. Studies to examine the association of cognitive impairment analgesic and sedation strategies would be beneficial to improve the quality of life of ICU survivors.
methodsA prospective clinical trial was designed to compare the effects of two drugs, propofol, and dexmedetomidine, on short-term cognitive impairment after sedation in elderly ICU survivors by evaluating the extent of independence limited by the dementia-related activities of daily livings (ADLs). The plasma concentrations of brain injury biomarkers including S100β and neuron-specific enolase (NSE) were determined using an enzyme immunoassay. There were 136 patients allocated into both the dexmedetomidine group and the propofol group, respectively, with matched demographic characteristics.
resultsThe dementia scale of the patients in the dexmedetomidine group was significantly higher than the propofol group at weeks 1-4. Moreover, the changes in S100β and NSE concentrations in the dexmedetomidine group were significantly more pronounced than the propofol group. ICU patients who received dexmedetomidine intervention showed higher cognitive impairment than patients who received propofol, and this protective effect of propofol was not associated with the levels of brain injury markers S100β and NSE.
conclusionOur study compared the effects of commonly used medications on short-term cognitive impairment in elderly ICU patients, which would aid the selection of sedation plan for the benefit of ICU patients.
