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 aimed to compare the reliability and validity of various prediction models based on load-velocity relationships for predicting the one-repetition maximum (1 RM) in Bulgarian split squat (BSS) exercises. Twenty-seven resistance-trained men participated in the study, completing both a 1-RM test and a progressive loading test to determine the 1 RM value, along with the mean velocity (MV) and peak velocity (PV) for each load. Load-velocity relationships were constructed using linear and binomial regression equations. The results revealed a strong correlation between different velocities and relative loads in BSS exercises (R
