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
Background Management of elderly patients with Non-ST Elevation Myocardial Infarction (NSTEMI) continues to be a source of controversy due to underrepresentation in large-scale clinical trials and the increased risk of adverse outcomes after both invasive (Percutaneous coronary intervention and Coronary artery bypass grafting) and non-invasive therapies. Recent randomized clinical trials have shown improved short term and intermediate term outcomes among high risk NSTEMI patients receiving early invasive management versus conservative medical management. However, how this is reflected in U.S. clinical practice for elderly patients has not been reported. Objective To identify the trend of invasive management in patients with NSTEMI, particularly among elderly population. Methods We used data from National Hospital Discharge Survey to identify all adult patients with an International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code for NSTEMI from the years 2005 to 2009. The goal was to investigate the trends in time of invasive therapy for patients diagnosed with NSTEMI. We then stratified the patients according to age >65 and ≤65, and compared the temporal trends between two age groups. Results Among 21,306 patients diagnosed with NSTEMI between 2005 and 2009, the median age was 73 years (IQR: 61-82 years), 54% were males and 57% were White. The proportions of patients age>65 years receiving invasive management (21%, N=13978) was significantly lower than those age≤65 (41%, N=7328) (p<0.001). Moreover, in both age groups, the proportion of patients receiving early invasive management decreased substantially over time (p<0.001). Conclusion Despite numerous studies promoting the use of early invasive management for NSTEMI patients, the proportion of patients receiving invasive intervention gradually decreased from 2005-2009, more so in elderly population. The decrease seen in overall proportion of patients receiving invasive therapy could be associated with older median age of NSTEMI patients; 73 years (IQR: 61-82). Our future analyses will investigate if this trend maintains after adjusting for other factors (sex, co-morbid conditions, insurance status, year of procedure, hospital region, and hospital bed-size) thought to be associated with the management of NSTEMI in elderly patients.
