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

The aims of this study were: (1) to verify the validity of previous proposed models to estimate the lowest exercise duration (TLOW) and the highest intensity (IHIGH) at which VO2max is reached (2) to test the hypothesis that parameters involved in these models, and hence the validity of these models are affected by aerobic training status. Thirteen cyclists (EC), eleven runners (ER) and ten untrained (U) subjects performed several cycle-ergometer exercise tests to fatigue in order to determine and estimate TLOW (ETLOW) and I HIGH (EIHIGH). The relationship between the time to achieved VO2max and time to exhaustion (Tlim) was used to estimate ETLOW. EIHIGH was estimated using the critical power model. IHIGH was assumed as the highest intensity at which VO2 was equal or higher than the average of VO2max values minus one typical error. TLOW was considered Tlim associated with IHIGH. No differences were found in TLOW between ER (170 +/- 31 s) and U (209 +/- 29 s), however, both showed higher values than EC (117 +/- 29 s). IHIGH was similar between U (269 +/- 73 W) and ER (319 +/- 50 W), and both were lower than EC (451 +/- 33 W). EI HIGH was similar and significantly correlated with IHIGH only in U (r = 0.87) and ER (r = 0.62). ETLOW and TLOW were different only for U and not significantly correlated in all groups. These data suggest that the aerobic training status affects the validity of the proposed models for estimating IHIGH.
