Association between systemic immune-inflammatory markers and monoclonal gammopathy of undetermined significance in the elderly population: findings from the National health and nutrition examination survey.

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
backgroundMonoclonal gammopathy of undetermined significance (MGUS) is a premalignant plasma cell disorder whose prevalence increases with age and may progress to multiple myeloma. The tumor microenvironment plays a crucial role in MGUS pathogenesis and progression. Systemic immune-inflammatory markers can reflect tumor microenvironment(TME) dynamics, but their association with MGUS odds remains understudied.
methodsThis cross-sectional study analyzed data from 12,080 adults aged ≥ 50 years (including 350 MGUS cases) in the National Health and Nutrition Examination Survey (NHANES III and 1999-2004 cycles). Multivariable logistic regression assessed associations between systemic immune-inflammatory markers [lymphocyte-to-monocyte ratio(LMR), Platelet-to-lymphocyte ratio(PLR), Hemoglobin, albumin, lymphocyte, platelet score(HALP), and their individual components] and MGUS. Generalized additive models identified nonlinear relationships and threshold effects across stratified groups.
resultsHigher LMR quartiles were positively associated with MGUS prevalence (Q4 vs. Q1: OR = 1.454, 95% CI 1.048-2.016), while elevated monocyte counts (OR = 0.624, 95% CI 0.456-0.853) and albumin levels (OR = 0.446, 95% CI 0.317-0.627) correlated with reduced MGUS odds. Nonlinear analysis revealed a U-shaped association between PLR and MGUS. There are race-specific nonlinear correlations involving LMR, PLR, and lymphocyte counts with MGUS.
conclusionsSystemic immune-inflammatory markers are significantly associated with MGUS odds in older adults, highlighting their potential for early detection and longitudinal monitoring.
