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
BACKGROUND Minimally invasive intramedullary nail (IMN) fixation has gained increasing attention for proximal humerus fractures. We compared operative time, intraoperative blood loss, postoperative pain, and functional outcomes between minimally invasive IMN fixation and locking plate fixation. MATERIAL AND METHODS This prospective study enrolled 61 patients from January 2019 to January 2024: 36 treated via IMN (Group A) and 25 treated via locking plates (Group B). Operative time, incision length, blood loss, visual analog scale (VAS) scores, complication rates, and postoperative shoulder function were analyzed. RESULTS Group A had a shorter operative time, smaller incision length, less blood loss (all P=0.001); shorter hospital stay (P=0.006); lower VAS scores (P=0.04); and fewer complications (P=0.03) than Group B. Group A demonstrated better shoulder flexion at 1, 3, and 6 months (P<0.001; =0.003, 0.029). At 1, 3, 6, and 12 months, Group A showed superior external rotation, internal rotation, and abduction versus Group B (all P<0.05). The neck-shaft angle was greater and loss of humeral head height was lower in Group A at 3, 6, and 12 months (all P<0.05). Constant-Murley scores were higher in Group A at 1 and 3 months (P=0.008, 0.032); DASH scores were lower in Group A at 3 and 12 months (P=0.002, 0.009). CONCLUSIONS IMN fixation for proximal humerus fractures offers shorter operative time, fewer complications, and improved postoperative shoulder function, indicating superior clinical efficacy relative to locking plate fixation.
