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

Monitoring patellar tendon stiffness may provide new insights into tendon adaptation due to loads and pathology. This 12-week prospective observational pilot study aimed to determine the feasibility of monitoring patellar tendon stiffness in relation to training load, pain, and function in male talent volleyball players. Feasibility outcomes included willingness to participate and retention rate, measurement completeness, and adverse events. Willingness to participate and retention rate were 100% in the included 15 volleyball players. Measurement completeness was below the pre-defined success criteria: 72% for stiffness before training and 66% after training; 52% for internal load and 38% for external load; 71% for experienced pain measurements; and 68% for questionnaire completion. This feasibility study indicates that there are several challenges in obtaining a complete data set when monitoring talented volleyball players. Communication between researcher-coach-athlete, feedback on collected data, and education on the importance of maintaining (tendon) health can be considered important factors to overcome these challenges.
