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
aimWith the advent of an aging society and the development of end-of-life care, there is an increasing need to understand the older generation's attitude toward end-of-life resuscitation. The study aimed to develop and validate a novel attitude scale toward end-of-life resuscitation in older inpatients.
methodInstrumental development and a psychometric evaluation were used. First, a new attitude scale toward end-of-life resuscitation was formulated from literature views, expert content validity, and face validity. Next, the new scale was evaluated using a principal component analysis and internal consistency reliability in a sample from 106 medical-surgical inpatients in a southern Taiwan hospital 1 enrolled through convenience sampling. Serving as an indicator of concurrent validity, a logistic regression analysis was performed to analyze the association between scores on the scale and intention to discuss end-of-life CPR issues.
resultsAfter being validated by the expert content validity and face validity, a draft of a 20-item scale was created. Throughout the exploratory factor analysis, two items with low factor loadings were removed from the draft scale and an 18-item scale of attitude was generated. This 18-item scale had a three-factor structure that accounted for 64.1% of the total variance; the three components were named 'stress, avoidance, and ignorance', 'a peaceful death', and 'self-determination and ambivalence'. The Cronbach's alpha of the total scale and three components were 0.845, 0.885, 0.879, and 0.857, respectively, which indicated a favorable reliability. Scores on the scale were significantly associated with the intention to discuss end-of-life CPR issues, which also indicated a favorable concurrent validity.
conclusionsA 18-item attitude scale with three factors is a valid scale to measure the attitude toward end-of-life resuscitation. The result provides preliminary evidence of the psychometric properties of the scale. Further research with larger samples or other populations is required.
