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 purpose of this study was to compare power outputs, and blood concentrations of lipid hydroperoxides (LH), malondialdehyde (MDA), creatine kinase (CK), myoglobin (Mb) and lactate ([La-]B) following 30 s of maximal cycle ergometry when resistive forces were derived from total-body mass (TBM) or fat-free mass (FFM). Alpha-tocopherol (AT), retinol (R) and uric acid (UA) concentrations were also measured to qualify the activity of antioxidants. Cardiac troponin levels were determined to exclude myocardial damage and to verify that any CK was predominantly derived from skeletal muscle. Differences (P<0.05) in peak power output, pedal velocity and resistive forces were observed when the TBM and FFM protocols were compared [953 (114) W vs 1,020 (134) W; 134 (8) rpm vs 141 (7) rpm; 6 (1) kg vs 5 (1) kg respectively). LH and MDA concentrations increased immediately post-exercise during the TBM protocol only (P<0.05) and were greater when compared to FFM (P<0.05). LH and MDA values decreased 24 h post-exercise. Increases in CK concentrations were recorded immediately post-exercise for both the TBM and FFM protocols with greater concentrations recorded for TBM (P<0.05). Decreases were observed 24 h post-exercise. Mb concentrations were greater immediately post-exercise for the TBM protocol and were greater than those recorded for FFM (P<0.05). Values decreased 24 h later (P<0.05). AT and UA concentrations decreased immediately post-exercise for both protocols (P<0.05) and increased 24 h later (P<0.05). There were no changes observed in R concentrations at any of the blood sampling stages. [La-]B increased (P<0.05) immediately post-exercise for both protocols, and decreased 24 h later (P<0.05). The results of the study suggest that greater power outputs are obtainable with significantly less oxidative stress and muscle disruption when resistive forces reflect FFM mass as opposed to TBM.
