1 · What the graph read from it

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.

2 · The registry

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

Purpose: To investigate the impact of subclinical hypothyroidism (SCH) and thyroid autoimmunity (TAI) on systemic inflammatory activity in women with normogonadotropic anovulation, comparing polycystic ovary syndrome (PCOS) and hypothalamic-pituitary-ovarian dysfunction (HPOD), and to examine the correlations of inflammatory parameters with thyroid, metabolic, and ovarian indices. Methods: Concentrations of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6, interleukin-1β, and interleukin-10 were prospectively measured in anovulatory women and compared between those with PCOS and HPOD, considering the influence of SCH and TAI. Multiple regression analysis was performed to evaluate the relationships among thyroid dysfunction, inflammatory parameters, and indices of both metabolic and ovarian function. Results: Both SCH and TAI independently increased TNF-α concentrations across the entire cohort (p=0.005 and p=0.018) and within the PCOS arm (p=0.018 and p=0.039). TAI significantly elevated the IL-1β/IL-10 ratio in the entire cohort (p=0.009) and in PCOS arm (p=0.005), with significant interaction effects between SCH and TAI in both groups (p=0.026 and p=0.017). No significant associations were found in the HPOD arm. In the overall cohort, CRP concentrations, which positively correlated with BMI, insulin resistance indicators, and dyslipidemia, and negatively with estradiol, were significantly higher in SCH (p-values <0.001). In PCOS, interleukin-1β and TNF-α levels, positively correlated with some insulin resistance indicators and TNF-α with AMH, were also significantly elevated in both SCH and TAI. Conclusions: SCH and TAI independently and synergistically promoted chronic inflammation in normogonadotropic anovulation, particularly in PCOS, through elevated TNF-α and disrupted interleukin-1β/IL-10 balance, with significant implications for metabolic health and ovarian function.
