Limited association between multimorbidity and high-sensitive C-reactive protein or gait speed in community-dwelling octogenarians - findings from the BUTTERFLY study.

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
backgroundBiological age is a key determinant of disease progression and increased morbidity. However, it is unclear whether multimorbidity is associated with low-grade inflammation or gait speed in octogenarians.
aimTo examine cross-sectional associations between commonly used comorbidity indices and either elevated high-sensitivity C-reactive protein (hsCRP) or reduced gait speed in community-dwelling non-frail adults aged 80 and older.
methodsa total of 404 community-dwelling older adults (mean age: 83 ± 3 years) were assessed for multimorbidity, gait speed, and hscrp. five comorbidity indices were calculated: charlson comorbidity index, cumulative illness rating scale for geriatrics, elixhauser comorbidity index (eci), rockwood frailty index, and a weighted modified disease count. binary logistic regression was used to analyze associations with elevated hscrp (>3.0 mg/l) and reduced gait speed (<0.8 m/s).
resultsOf the indices evaluated, only the ECI showed a significant association with elevated hsCRP (adjusted odds ratio [aOR] = 1.18, 95% CI: 1.03-1.35; p = 0.020). When stratified by gender, this association remained significant in men (aOR = 1.29, 95% CI: 1.053-1.59; p = 0.014), but not in women. Furthermore, none of the comorbidity indices were significantly associated with low gait speed.
conclusionAmong the comorbidity indices assessed, only the ECI demonstrated a modest yet significant association with hsCRP levels in individuals aged 80 years and older. In contrast, no significant associations were observed between any of the comorbidity indices and reduced gait speed in this population. This highlights the importance of comprehensive care, including individualized lifestyle interventions, nutritional support, and timely pharmacological adjustments for effective chronic disease management.
