Perceived exertion and blood lactate concentration during graded treadmill running.
Trial report in European journal of applied physiology and occupational physiology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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 purpose of this study was to investigate the influences of treadmill gradients on the rating of perceived exertion (RPE) at two fixed blood lactate concentrations ([La-]b). Ten subjects performed three different incremental treadmill protocols by running either uphill (concentrically-biased), downhill (eccentrically-biased), or on the flat (non-biased). Individual data of each protocol were interpolated to reflect [La-]b corresponding to 2.0 and 4.0 mmol.l-1. At 2.0 mmol.l-1 [La-]b, RPE and treadmill speed during downhill running were greater than during level running which was greater than during uphill running (p < 0.05). Also, the downhill heart rate (HR) was greater than the uphill HR, and downhill minute ventilation (VE) was greater than the level VE. Treadmill speed was the only measure at 4.0 mmol.l-1 [La-]b to differ between gradients. There was a moderate correlation of RPE with HR at both [La-]b (r = 0.73 at 2.0 mmol.l-1; r = 0.48 at 4.0 mmol.l-1) while treadmill speed was moderately correlated with RPE only at 2.0 mmol.l-1 [La-]b (r = 0.70). The results of this study demonstrated that the degree of eccentric-bias during running exercise is an influence of perceived exertion at a moderate but not at a high exercise intensity.
