Normative data for insulin-like growth factor-1 and insulin-like growth factor binding protein-3 and their determinants in healthy adult males from india: the INDIIGo study.
Article in Scientific reports, 2025. 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
The INDIIGo study aimed to establish normative data for serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) in adult Indian males, addressing the paucity of data for the South East Asian population. This cross-sectional study included 1271 healthy males aged 20 to 65.9 years from Chandigarh, India, with measurements obtained using the Roche Elecsys electrochemiluminescence immunoassay (ECLIA). Age-specific normative centile curves were generated using the LMS (Lambda, Mu, Sigma) method. Serum IGF-1 levels declined by 30.1 ng/ml per decade (95% CI - 34.9 to - 25.2; p < 0.001) and were negatively associated with lower socioeconomic status (- 5.8 ng/ml per class; p = 0.002), ALT (- 0.6 ng/ml per unit; p < 0.001), and HbA1c (- 8.2 ng/ml per category; p = 0.04). Positive correlations were observed with serum T4 (+ 4.5 ng/ml per unit; p < 0.001) and serum albumin (+ 18.0 ng/ml per g/dL; p = 0.009). IGFBP-3 levels decreased by 447.8 ng/ml per decade (95% CI - 547.6 to - 348.1; p < 0.001), with a significant positive association with serum T4 (+ 60.8 ng/ml per unit; p = 0.025). This study provides age-specific normative data for IGF-1 and IGFBP-3 in Indian males and identifies key factors influencing these biomarkers.
