Values are means ± SDs or means (ranges) unless otherwise indicated. Forty-five studies met the inclusion criteria and assessed IL-6 before and after the consumption of an HFM. If studies separately assessed different groups, those specific subsets are specified alongside the study. HFM, high-fat meal; MO, main outcome (whether or not IL-6 was the main outcome being studied); N, no; NS, not stated; NW, normal weight; P, plasma; PPP, length of postprandial period assessment; QA, quality appraisal; S, serum; TTP, time to peak or maximal observed concentration if a significant change was detected; Y, yes; ↑, significant increase; ↓, significant decrease; ↔, no significant change; —, not applicable; %E, percentage of energy.
Percentage of energy in the test meal from fat.
Baseline or fasting concentration of the marker.
Peak or maximal observed concentration of the marker.
