Effects of high-intensity interval training on physical fitness and body composition in recreationally active females: a systematic review and meta- analysis.
Synthesis in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
High-intensity interval training (HIIT) is recognized as a time-efficient and effective strategy for enhancing physical fitness and body composition in a shorter duration compared to traditional training protocols. However, there is limited evidence regarding its effects in recreationally active females, as physiological adaptations may differ from those observed in elite athletes and clinical populations. This systematic review and meta-analysis aimed to evaluate the efficacy of HIIT in improving physical fitness and body composition in recreationally active females and to identify potential moderators influencing training outcomes. A comprehensive literature search was conducted across three databases (PubMed, Web of Science, and Scopus) up to February 2024. Studies were included if they examined the effects of HIIT interventions on physical fitness and body composition in recreationally active females (≥ 150-300 min/week moderate-intensity or ≥ 75-150 min/week vigorous-intensity aerobic activity, ≥ 2 days/week muscle-strengthening exercise) without age restrictions. A total of 15 studies met the inclusion criteria, comprising a pooled sample of 304 female participants (age: 25.1 ± 4.2 years old). The findings demonstrated significant, yet small, improvements in maximal oxygen uptake (VO
