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
purposeThe present study aimed to investigate the influence of preoperative TTE on postoperative short-term mortality, surgery delay, as well as other economic and clinical outcomes in Chinese geriatric hip fracture patients.
methodsThis retrospective, matched-cohort study enrolled geriatric hip fracture patients (≥ 60 years) who underwent surgical interventions at our center between 2015 and 2020. The primary exposure was inpatient preoperative TTE. Demographic and clinical data that were reported as risk factors for postoperative mortality were retrieved from the medical data center as the covariates. The primary clinical outcomes were all-cause mortality at 30 days, 90 days, 180 days, and 1 year. Time from hospital presentation to surgery, length of stay (LOS), inpatient cost, frequency of cardiology consultation and coronary angiography (CAG) were also assessed. The propensity score matching (PSM) was performed in a ratio of 1:1.
results447 patients were identified and 216 of them received a preoperative TTE (48.3%). After successfully matching 390 patients (87.2%), patients receiving TTE showed significantly higher 30-day mortality (6.6% vs 2.0%, P = 0.044). But no significant difference was found in 90-day, 180-day, and 365-day mortality as well as the 1-year accumulated survival rate. Receipt of TTE was also associated with significant increases in LOS (13.6 days vs 11.4 days, P = 0.017), waiting time for surgery (5.9 days vs 4.3 days, P < 0.001), and lower proportion of receiving surgery within 48 h (7.2% vs. 26.2%, P < 0.001). According to the multivariable logistic analysis, only ejection fraction (30 days, 90 days), aorta diameter (30 days, 90 days, 180 days, 365 days), left ventricular posterior wall diameter (90 days, 180 days, 365 days), aortic valve velocity (90 days) and mitral valve A-peak (90 days, 180 days) were association with postoperative mortality among the 17 parameters in the TTE reports. Besides, TTE has no influence on the frequency of preoperative cardiology consultation.
conclusionPreoperative TTE does not lead to decreased postoperative mortality but with increased time to surgery and length of stay in Chinese geriatric hip fracture patients. The predictive ability of TTE parameters is limited for postoperative mortality.
