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

This study investigates the physiological effects of intensive physical training on femoral cartilage morphology and limb asymmetry in strength in air force cadets. Thirty male cadets were evaluated using ultrasonography to measure femoral cartilage thickness, isokinetic testing to assess knee flexor and extensor strength, and the functional movement screen (FMS) to examine movement patterns. Participants were divided into pass and fail groups based on the G test, a measure of gravitational acceleration tolerance. Cadets in the fail group exhibited significantly thinner cartilage in the medial condyle of the right knee and greater knee flexion asymmetry at 180°/s. The pass group demonstrated superior FMS performance, greater muscular strength, and less limb asymmetry. These findings suggest that repetitive mechanical loading during military training may lead to cartilage thinning and functional asymmetry, increasing the risk of musculoskeletal injury. Periodic musculoskeletal screening and targeted interventions could mitigate injury risks in occupational environments characterized by high physical demands.
