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.

Abstract
backgroundHigh-intensity functional training (HIFT) varies daily workout programming, and trainees are often tasked with completing "as many repetitions as possible" (AMRAP) within a set time. Successful performance depends on fatigue management skills and maintaining a consistent expression of force and velocity when performing and transitioning between exercises over the duration of the workout. Multi-ingredient pre-workout (MIPS) supplement formulations often contain ingredients shown to facilitate energy availability and mitigate fatigue, and therefore, might positively affect HIFT performance. This study aimed to assess a multi-ingredient pre-workout supplement's acute effect on pacing and the expression of kinetics throughout a 5- and 15-minute HIFT-style AMRAP.
methodsTwelve men and 10 women (29.3 ± 7.1 years, 171 ± 7 cm, 80.5 ± 15.6 kg) with HIFT experience ( > 2 years) completed four weekly visits, consuming either the supplement (S) or placebo (P) before a 5- or 15-minute AMRAP of rowing (9 or 7 Calories for men and women), six barbell thrusters (43.1 kg and 29.5 kg), and three jumps onto a box (0.61 m and 0.51 m). Video recordings of each workout were analyzed to quantify repetitions completed, volume load (kg), and pace (i.e. time spent on each workout component, repetition completion rate). The expression of kinetics and related factors were quantified during rowing via the ergometer microcomputer (Calories per stroke, power [W], and strokes per minute), during barbell thrusters by a 3D motion tracking system (barbell velocity [m · sec
resultsMen and women completed a greater total volume load (~4.4%,
conclusionsAlthough it did not affect repetitions completed, the multi-ingredient pre-workout supplement led to a greater volume load and faster overall repetition completion rate. These were primarily due to improvements surrounding rowing performance and evidence of an effect on thruster pacing and box jump force expression. The effects were similar in both sexes and workout durations. Athletes might consider this MIPS formulation to improve HIFT performance, particularly when a workout contains a component that requires sustained, continuous effort.
