Prevention of Cognitive Frailty in Patients of Older Age Groups after Open-Heart Surgery under Cardiopulmonary Bypass.
Article in Archives of Razi Institute, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Acute change in mental state is characterized by an impaired level of consciousness, decreased attention, and cognitive changes, and has a variable course throughout its period. Delirium is common in the elderly and hospitalized patients, especially after major surgeries, and increases mortality and morbidity in patients. This study was designed to investigate the relationship between the incidence of delirium after heart surgery and some intrusive factors during surgery. A total of 263 middle-aged, elderly, and chronic patients with functional class III-IV heart failure were classified based on the New York Heart Association classification and valvular heart disease. Cognitive impairment screening was performed using the Mini-Cog test and clock drawing test in addition to standard general clinical examinations on patients. Cognitive impairment was diagnosed in patients with coronary heart disease preparing for planned surgical treatment, regardless of age, while the results of both tests were significantly worse in elderly patients than in their middle-aged counterparts. In the early postoperative period, both among the middle-aged and elderly patients, there was a significant improvement in the results of the clock drawing test. Middle-aged patients also showed improved results on the Mini-Cog test, while the elderly patients showed an increase in cognitive dysfunction. In the third stage of the examination of cognitive function in the two studied groups of patients with valvular pathology at the first checkpoint, no statistically significant differences were found in the Mini-Mental State Examination (MMSE), Mini-Cog, and clock drawing test. The results of the clock drawing test in the main and control groups were recorded at 8.9±0.4 and 5.8±0.3 points, respectively (
