High cycling cadence reduces carbohydrate oxidation at given low intensity metabolic rate.

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
Cycling cadence (RPM)-related differences in blood lactate concentration (BLC) increase with increasing exercise intensity, whilst corresponding divergences in oxygen uptake ([Formula: see text]O2) and carbon dioxide production ([Formula: see text]CO2) decrease. Aim of the present study was to test whether a higher RPM reduces the fraction (%) of the [Formula: see text]O2 used for carbohydrate oxidation (relCHO) at a given BLC. Eight males (23.9 ± 1.6 yrs; 177 ± 3 cm; 70.3 ± 3.4 kg) performed incremental load tests at 50 and 100 RPM. BLC, [Formula: see text]O2 and [Formula: see text]CO2 were measured. At respiratory exchange ratios (RER) < 1, relCHO were calculated and the constant determining 50 % relCHO (kCHO) was approximated as a function of the BLC. At submaximal workload [Formula: see text]O2, [Formula: see text]CO2, and relCHO were lower (all p < 0.002; η(2) > 0.209) at 50 than at 100 RPM. No differences were observed in [Formula: see text]O2peak (3.96 ± 0.22 vs. 4.00 ± 0.25 l · min (-1)) and RERpeak (1.18 ± 0.02 vs. 1.15 ± 0.02). BLC was lower (p < 0.001; η(2) = 0.680) at 50 than at 100 RPM irrespective of cycling intensity. At 50 RPM, kCHO (4.2 ± 1.4 (mmol · l (-1))(3)) was lower (p = 0.043; η(2) = 0.466) than at 100 RPM (5.9 ± 1.9 (mmol · l (-1))(3)). This difference in kCHO reflects a reduced CHO oxidation at a given BLC at 100 than at 50 RPM. At a low exercise intensity, a higher cycling cadence can substantially reduce the reliance on CHO at a given metabolic rate and/or BLC.
