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
Sodium bicarbonate (SB) and betaalanine (BA) can enhance high-intensity exercise performance. This study examined the effects of eight weeks of resistance training combined with these supplements on muscle cross-sectional area (CSA), serum myostatin and interleukin-15 concentration, and upper- and lower-body muscular strength and power. Twenty active males (age: 18-35) were divided into supplement (SUP) and placebo groups (PL; each group n=10). Participants undertook eight weeks of supervised resistance training, including 3 sessions × 3 sets × maximum repetitions at 70% of 1RM. Supplementations included 3-6 g/day BA and 4-6 g/day SB administered for 8 weeks. Exercise volume, calculated as the total number of repetitions completed in each session, increased to a greater extent following SUP (~29%) than PL (~13%) groups (P=0.014). Central segment of quadriceps CSA, measured using magnetic resonance imaging, demonstrated a greater increase following SUP compared to PL for both right ((~21%; pre to post: 452.47±55.98 to 548.21±73.92 mm
