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

Sex differences in running economy (gross oxygen cost of running, CR), maximal oxygen uptake (VO2max), anaerobic threshold (Th(an)), percentage utilization of aerobic power (% VO2max), and Th(an) during running were investigated. There were six men and six women aged 20-30 years with a performance time of 2 h 40 min over the marathon distance. The VO2max, Th(an), and CR were measured during controlled running on a treadmill at 1 degree and 3 degrees gradient. From each subject's recorded time of running in the marathon, the average speed (vM) was calculated and maintained during the treadmill running for 11 min. The VO2max was inversely related to body mass (mb), there were no sex differences, and the mean values of the reduced exponent were 0.65 for women and 0.81 for men. These results indicate that for running the unit ml.kg-0.75.min-1 is convenient when comparing individuals with different mb. The VO2max was about 10% (23 ml.kg-0.75.min-1) higher in the men than in the women. The women had on the average 10-12 ml.kg-0.75.min-1 lower VO2 than the men when running at comparable velocities. Disregarding sex, the mean value of CR was 0.211 (SEM 0.005) ml.kg-1.m-1 (resting included), and was independent of treadmill speed. No sex differences in Th(an) expressed as % VO2max or percentage maximal heart rate were found, but Th(an) expressed as VO2 in ml.kg-0.75.min-1 was significantly higher in the men compared to the women. The percentage utilization of fcmax and concentration of blood lactate at vM was higher for the female runners.(ABSTRACT TRUNCATED AT 250 WORDS)
