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

backgroundPentoxifylline (PTX), a methylxanthine derivative, has been recognized as a potential anti-inflammatory treatment across various conditions, yet its effects on inflammatory markers remain inconsistent. This systematic review/meta-analysis evaluated the impact of PTX on serum levels and gene expression of key inflammatory markers in randomized controlled trials (RCTs).

methodsA systematic search was conducted in PubMed, Scopus, Embase, Web of Science, and ProQuest up to May 2025. Search results were screened in two stages by two independent reviewers. Data was extracted and the quality of the studies included was assessed using the Cochrane Risk of Bias (RoB) tool. Statistical analysis was performed using STATA -17. The present study was conducted in accordance with the PRISMA guidelines.

resultsThis study included 81 RCTs involving 7,058 participants. PTX treatment significantly reduced serum levels of CRP (SMD = -0.30, 95% CI: -0.47 to -0.13), IL-6 (SMD = -0.51, 95% CI: -0.81 to -0.22), TNF-α (SMD = -0.72, 95% CI: -0.95 to -0.48), and IL-8 (SMD = -1.14, 95% CI: -1.94 to -0.33) compared to controls. No statistically significant effects were observed for IL-1β, ESR, IL-10, or TNFR. High heterogeneity was noted in most outcomes, partly attributed to variations in age, treatment duration, dosage, geographic region, and health conditions. Subgroup analyses revealed that younger patients, shorter interventions, and lower PTX doses were associated with stronger anti-inflammatory responses.

conclusionPTX reduces TNF-α, IL-6, IL-8, and CRP, supporting its role in chronic inflammatory diseases. Efficacy varies by age, dose, duration, geography, and disease, requiring personalized treatment. Contradictory biomarker effects and study limitations warrant high-quality trials with standardized protocols.
