Application Value of Chemiluminescence Immunoassay in Thyroid Function Biochemical Testing.
Article in Journal of fluorescence, 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
objectiveTo evaluate the application value of chemiluminescence immunoassay (CLIA) in thyroid function biochemical testing.
methodsThis study included 147 patients, classified into five thyroid function groups: overt hypothyroidism (n = 10), subclinical hypothyroidism (n = 33), euthyroidism (n = 61), subclinical hyperthyroidism (n = 14) and overt hyperthyroidism (n = 29). Thyroid function tests, including total triiodothyronine, total thyroxine, free triiodothyronine, free thyroxine, thyroid-stimulating hormone (TSH) and thyroid autoantibodies (anti-thyroid peroxidase [anti-TPO], anti-thyroglobulin), were measured using the MAGLUMI X8 CLIA analyser. Thyroid ultrasound was performed using a Hitachi Aplio500 system. Statistical analyses included one-way ANOVA, Kruskal–Wallis testing, correlation analysis and multivariate logistic regression.
resultsSignificant differences in thyroid function parameters were observed among the groups. The overt hypothyroidism group showed elevated TSH (12.2 ± 11.2 mIU/L, p < 0.001) compared with the euthyroid group. The hyperthyroidism groups demonstrated elevated thyroid hormones with suppressed TSH (0.1 ± 0.1 mIU/L, p < 0.001). Both hypothyroidism and hyperthyroidism groups had higher thyroid autoantibody concentrations, with 45% and 52% of patients showing levels above the reference range, respectively, compared with 15% in the euthyroid group (p < 0.001). Multivariate analysis identified elevated TSH (odds ratio [OR] = 1.10, 95% confidence interval [CI]: 1.05–1.15), FT4 (OR = 1.05, 95% CI: 1.02–1.08) and anti-TPO antibodies (OR = 1.01, 95% CI: 1.00–1.02) as independent predictors of thyroid dysfunction. Method comparison studies showed excellent correlation with enzyme immunoassay methods (r = 0.90–0.93).
conclusionThe CLIA method effectively differentiates between patient groups with varying thyroid function status by accurately measuring thyroid hormones, TSH and autoantibodies. It provided reliable results that aligned with clinical presentations and supported diagnostic decision-making.
