Preoperative ECG Abnormalities Among Patients Who Underwent Elective Surgical Operations at the Kuwaiti Specialised Hospital, Khartoum, Sudan: A Cross-Sectional Study.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe presence of preoperative ECG abnormalities has shown wide variation, and its value has been argued; thus, this study aimed to determine preoperative ECG abnormalities among Sudanese patients and their correlates. MATERIALS AND
methodsAn observational descriptive cross-sectional study was conducted at the Kuwaiti Specialised Hospital, Khartoum, Sudan, from October 2020 to March 2021, including all patients over 40 years of age who planned to undergo elective surgery. Demographic, clinical, and ECG findings were obtained during the pre-anaesthesia check-up. The data were analysed using IBM SPSS software version 28 (IBM Corp., Armonk, NY).
resultsThe study included a total of 304 patients with a mean age of 60±14 years, a male predominance of 210 (69.1%) patients, the presence of hypertension (HTN) in 65 (21.4%), and diabetes mellitus (DM) in 58 (19.1%) patients. The study showed that 235 (77%) patients had at least one ECG abnormality. However, 62 (20.4%) were diagnosed as having normal ECG variations; the most commonly diagnosed abnormality was ischemic heart disease (IHD) (32.5%), followed by sinus tachycardia (39, 12.8%). The QRS complex abnormalities were the most common (100, 32.9%), with M-shaped QRS (RSR pattern) being the most common single ECG abnormal sign (65, 21.4%). The ECG abnormalities showed no significant association with age (p-value = 0.24), gender (p-value = 0.16), DM (p-value = 0.77), HTN (p-value = 0.35), asthma (p-value = 0.35), or the grade of surgery (p-value = 0.52). However, the diagnosis of IHD was associated with the presence of HTN (p-value = 0.001).
conclusionIncidental preoperative ECG abnormalities are common among Sudanese patients undergoing elective surgery, affecting more than three-quarters of them and being of diagnostic value as they led to the diagnosis of ischemic heart disease in nearly one-third of patients. Hypertensive patients may benefit from routine preoperative ECG testing, as ECG signs of ischemic heart disease are more common among hypertensive patients.
