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

Background: Antioxidants and nitric oxide (NO) precursors may improve endurance exercise performance by reducing oxidative stress and increasing NO production. Almonds, dried grapes, and cranberries (AGC) are good sources of antioxidants and NO precursors. Objectives: To determine whether AGC consumption improved physiological responses and endurance cycling time-trial performance in response to training. Methods: After 1 wk of light training (LT), 96 male recreationally trained cyclists consumed 125 g of AGC or control (CON: isocaloric oat bar) daily during 2 wk of heavy training (HT) and a 2-wk taper (T). At the end of LT, HT, and T, endurance exercise performance (5-min cycling time-trial; 5CTT), NO bioavailability (plasma and urine nitrate and nitrite), oxidative stress [plasma F2-isoprostanes (F Results: Compared to LT, 5CTT performance was impaired at HT ( Conclusions: Although not beneficial for 5CTT performance or exercise efficiency, AGC increases fat oxidation during exercise, NO bioavailability, and subjective energy concentrations, which may confer benefits for health and wellbeing.This trial was registered at www.anzctr.org.au as ACTRN12618000360213.
