Mid-term outcomes of patients with subclinical hypothyroidism after coronary bypass surgery.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesSubclinical hypothyroidism (SCH) is characterized by an elevated thyroid-stimulating hormone and normal free thyroxine. This study aimed to evaluate the influence of SCH on mid-term outcomes of patients after coronary artery bypass grafting (CABG).
methodsFrom January 2015 to December 2018, 548 SCH patients and 6718 euthyroid patients who underwent CABG were identified. Propensity score matching was used to create 2 cohorts with similar baseline characteristics (n = 544 in each group). The mid-term follow-up outcomes were compared. Adjusted hazard ratios (HRs) were calculated using Cox proportional hazards models.
resultsThe mean follow-up for all patients was 39.7 ± 17.3 months. The unadjusted Kaplan-Meier estimate for mortality at 5-year follow-up was higher in patients with SCH compared with euthyroid patients (5.3% vs 1.6%, log-rank P = 0.03). After adjusting for covariates, the risk of mortality was higher in patients with SCH compared with euthyroid patients [HR, 2.40; 95% confidence interval (CI), 1.03-5.58; P = 0.04]. The adjusted risk of major adverse cardiovascular and cerebral event (HR, 2.16; 95% CI, 1.51-3.08; P < 0.001) and angina (HR, 2.44; 95% CI, 1.41-4.24; P = 0.001) was higher in patients with SCH compared with euthyroid patients.
conclusionsSCH is associated with an increased risk of mortality, major adverse cardiovascular and cerebral event and angina compared with euthyroidism in patients undergoing CABG.
