The effect of polyphenols on cytokine and granulocyte response to resistance exercise.

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
This study examined the effect of resistance exercise on the production, recruitment, percentage, and adhesion characteristics of granulocytes with and without polyphenol (PPB) supplementation. Thirty-eight untrained men were randomized into three groups: PPB (n = 13, 21.8 ± 2.5 years, 171.2 ± 5.5 cm, 71.2 ± 8.2 kg), placebo (PL; n = 15, 21.6 ± 2.5 years, 176.5 ± 4.9 cm, 84.0 ± 15.7 kg), or control (CON; n = 10, 23.3 ± 4.3 years, 173.7 ± 12.6 cm, 77.3 ± 16.3 kg). Blood samples were obtained pre (PRE), immediately (IP), 1 h (1H), 5 h (5H), 24 h (24H), 48 h (48H), and 96 h (96H) postresistance exercise (PPB/PL) or rest (CON). Fine-needle biopsies were obtained from the vastus lateralis at PRE, 1H, 5H, and 48H. Plasma concentrations and intramuscular content of interleukin-8 (IL-8), granulocyte (G-CSF), and granulocyte-macrophage colony stimulating factor (GM-CSF) were analyzed via multiplex assays. Changes in relative number of circulating granulocytes and adhesion receptor (CD11b) were assessed using flow cytometry. Intramuscular IL-8 was significantly elevated at 1H, 5H, and 48H (P < 0.001). Area under the curve analysis indicated a greater intramuscular IL-8 content in PL than PPB (P = 0.011). Across groups, circulating G-CSF was elevated from PRE at IP (P < 0.001), 1H (P = 0.011), and 5H (P = 0.025), while GM-CSF was elevated at IP (P < 0.001) and 1H (P = 0.007). Relative number of granulocytes was elevated at 1H (P < 0.001), 5H (P < 0.001), and 24H (P = 0.005, P = 0.006) in PPB and PL, respectively. Across groups, granulocyte CD11b expression was upregulated from PRE to IP (P < 0.001) and 1H (P = 0.015). Results indicated an increase in circulating CD11b on granulocytes, and IL-8 within the muscle following intense resistance exercise. Polyphenol supplementation may attenuate the IL-8 response, however, did not affect granulocyte percentage and adhesion molecule expression in peripheral blood following resistance exercise.
