Variations in energy and nutrient intake across competitive-season phases in relation to athletes' competitive schedule: the case of university male track and field jumpers by competitive level.

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
purposeAppropriate dietary intake across different training phases is crucial for improving the performance of track and field jumpers. However, few studies have investigated dietary intake based on the training phase and competitive level. The purpose of this study was to evaluate dietary intake in track and field jumpers across different training phases and competitive levels.
methodsA total of 28 male collegiate jumpers participated. A food frequency questionnaire assessing 1-month dietary intake was administered four times: transition phase (TP), preparatory phase (PP), early competitive phase (ECP), and late competitive phase (LCP). Participants were divided into the Exceeded Group (EG) and the Nonexceeded Group (NEG) based on competition standards.
resultsOf the 28 participants, 20 were included in the final analysis. Energy, protein, fat, vitamin B1, and vitamin B6 intake decreased during the ECP and LCP compared with intake during the TP. Intake of these nutrients was higher in the EG than in the NEG, with the EG significantly showing higher intake during the TP. However, these group differences were not observed during the LCP.
conclusionThese results indicate the necessity of appropriate dietary strategies for each training phase.
