Evaluating the association of ischemic ECG changes and CBC parameters in normal population.
Article in ARYA atherosclerosis, 2025. 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
backgroundFinding the relation between complete blood count (CBC) parameters and ischemic electrocardiogram (ECG) changes among a large normal population, for the first time.
methodsParticipants of the first phase of the MASHAD cohort study were enrolled in this cross-sectional study. Twelve-lead ECGs were taken from participants. According to the Minnesota codes, we divided the ischemic ECG changes into major and minor. Major ischemic changes included major Q-wave changes, minor Q-wave plus ST-T changes, and major isolated ST-T changes. Minor changes included minor isolated Q/QS waves, minor ST/T changes, and ST-segment elevation. The mean of the CBC parameters was compared between individuals with and without ischemic changes. The backward stepwise logistic regression model was implemented to estimate the odds ratios of ECG changes and eliminate confounders. Data were analyzed using SPSS version 20, with significance set at p < 0.05.
resultsAmong 9,106 participants, 510 individuals (5.6%) had minor and major ischemic changes, with a preference for males. Major ischemic changes were not associated with CBC parameters. However, the odds of having minor ischemic changes increased 1.96-fold with increasing red blood cell (RBC) count (OR = 1.96 [1.31-2.94], p = 0.001); though, they decreased by 0.18 units with increasing hemoglobin (OR = 0.81 [0.73-0.92], p = 0.001). Additionally, high mean corpuscular volume (MCV) increased the odds of minor ischemic changes (OR = 1.05 [1.01-1.08], p = 0.004).
conclusionAmong Mashhad's normal population, major ischemic changes were not associated with CBC parameters. Also, minor and major ischemic changes were positively associated with WBC count.
