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

purposeThe relatively recent advent of polyphenol supplement for exercise studies has been tested in a variety of forms and doses. However, the dose-response on adipokines and oxidative stress biomarker effect remains unknown. The aim of the present study was to assess the effect of intense, long-duration (48-h) exercise, and a single dose of proanthocyanidin, on plasma leptin, adiponectin, and electronegative low-density lipoprotein (LDL(-)) concentrations.

methodsFifty-four healthy male army cadets (22 ± 2 years) participated in a double-blind, randomized, placebo-controlled study and were distributed between control (CG; n = 27) and supplemented groups (SG; n = 27). Immediately before the start of the exercise, both CG and SG groups received a capsule containing starch (200 mg) or proanthocyanidin (dry Vitis vinifera extract, 200 mg), respectively. Following a 12-h fasting period, the plasma adiponectin, leptin, and LDL(-) concentrations were measured prior to the start of the exercise after 24 and 48 h of military training, and after 24 h of rest. The effects of the proanthocyanidin (supplement), exercise (time), and their interaction were investigated using factorial two-way ANOVA.

resultsPlasma leptin concentration was only influenced by exercise (p = 0.001). Plasma adiponectin concentration was influenced by exercise (p = 0.037), and by the exercise x supplement interaction (p = 0.033). LDL(-) was influenced by the supplement (p = 0.001), exercise (p = 0.001), and their interaction (p = 0.001).

conclusionsA single dose of proanthocyanidin (200 mg) was able to reduce LDL(-) concentration and increase plasma adiponectin concentration after 24 h of rest in SG group, indicating its potential protective action.
