Molecular Indicators of Isometric Exercise Efficacy in Early Rehabilitation of Older Adults After Total Hip Arthroplasty.
Article in International journal of molecular sciences, 2026. 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
Developing molecular methods for assessing the effectiveness of physical rehabilitation remains a pressing task. Our pilot study aimed to assess the utility of the transcriptome analysis of muscle biopsies in evaluating the efficacy of the isometric exercises (IEs) added to the standard protocol in the early rehabilitation of older patients during the initial two weeks post total hip arthroplasty (THA). Blood concentrations of total leukocytes, neutrophils, IL6, IL8, IL1β, myoglobin, etc. were measured, and transcriptome analysis of rectus femoris biopsies from the operated leg was performed before and after (1 and 12 days) THA in women aged 73-77 years. The additional IEs in the experimental rehabilitation group led to a significant acceleration in the recovery of IL6, IL8, and IL1β blood levels to the normal ranges compared to the control group, as confirmed by a Fisher's exact test for this cytokine combination. The results of Gene Set Enrichment Analysis and Differentially Expressed Gene Analyses for the muscle biopsies point to accelerated resolution of inflammation, along with enhanced activation of genes associated with angiogenesis, lymphangiogenesis, vasodilation, and vasoconstriction in the experimental rehabilitation group compared to the control group. Thus, IL6, IL8, and IL1β blood levels can serve in combination as molecular indicators of the efficacy of early rehabilitation after THA, and transcriptome analysis of the rectus femoris biopsies of the operated leg allows for the revelation of the molecular indicators of regenerative processes in muscle tissue near the surgery area after THA.
