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
Iatrogenic deep femoral artery (DFA) injury is a serious complication of hip surgery, often resulting from screw or wire placement in the femur owing to the limited visibility of the DFA and its branches during femoral penetration. We aimed to identify the course and location of DFA perforating branches using an imaging-based approach to improve surgical planning and prevent vascular injury during hip procedures, which has not been thoroughly evaluated in prior anatomical studies. We consecutively enrolled 20 female and 20 male participants with unilateral hip osteoarthritis. Contrast-enhanced computed tomography images of the unaffected side were used to identify the DFA. Associations between participant demographics and DFA branch location and trajectory were analyzed. The distance from the apex of the greater trochanter (GTR) to the first DFA perforating branch was significantly shorter in females than in males (mean: 100 (range, 77-122) vs. 113 (range, 99-131) mm, P < 0.001), whereas no significant difference was found for the second branch (mean: 154 (range, 108-242) vs. 160 (range, 128-235) mm, P = 0.73]. The DFA ran within 5 mm of the femur on the medial-posterior aspect at 140 mm and 200 mm distal to the apex of the greater trochanter, typical insertion sites for distal cortical screws in intramedullary nailing for hip fractures. In females, the first DFA perforating branch occurs more proximally than in males, necessitating caution during femoral wiring at this level. These findings help refine anatomical understanding of the DFA course, supporting safer surgical planning for intramedullary fixation. The small sample size (n = 40) is one of the limitations and may affect generalizability.
