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

A model that describes the blood lactate concentration (BLC) dynamics [BLC(t)] of a Wingate Anaerobic Test (WAnT) as a function of (a) BLC at the start of exercise (BLC(0)), (b) extra-vascular increase in lactate (A), (c) two corresponding velocity constants of appearance (k (1)) and disappearance (k (2)) of lactate into and out of the blood requires that BLC(0) is equal to resting BLC (BLC(rest)). We developed a model that considers an elevated BLC(0). 19 males performed WAnTs with warm-ups increasing (p < 0.001) BLC(0). The goodness of each individual fit improved (p < 0.05) if the difference between BLC(rest) and BLC(0) (DeltaBLC) was higher than 1.0 mmol l(-1). All differences between old and new model (p < 0.05) in A, k (1) and k (2) were interrelated with and increased with DeltaBLC (p < 0.05). The new model well describes BLC(t) and prevents substantial errors concerning lactate generation and dynamics if BLC(0) is elevated by more than 1.0 mmol l(-1).
