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
introductionNitinol continuous compression staples are increasingly used for foot and ankle arthrodesis; however, real-world outcome data describing construct strategies, regional variation in union, and failure patterns remain limited, particularly for Chopart joints.
methodsA retrospective case series of consecutive adult patients undergoing midfoot or Chopart arthrodesis using nitinol compression staples as the principal fixation method was performed. Arthrodeses were classified as midfoot (tarsometatarsal and/or naviculocuneiform) or Chopart (talonavicular and/or calcaneocuboid). Fixation constructs were categorised as staple-only or hybrid (staples combined with screws and/or plates). Radiographic union was defined as ≥50% trabecular bridging on two orthogonal radiographs or confirmation on computed tomography. The primary outcome was union rate; secondary outcomes included time to union, complications, reoperation, construct configuration, and failure patterns.
resultsTwenty-five arthrodeses were included (15 midfoot and 10 Chopart). Overall union was achieved in 22 of 25 procedures (88%). Union rates were higher in the midfoot cohort (14/15, 93.3%) than in the Chopart cohort (8/10, 80%). Median time to union among united procedures was 62 days (interquartile range: 47-80). Three non-unions (12%) and three complications (12%) occurred, with two procedures requiring further surgery. Staple-only constructs accounted for 20 procedures, with five hybrid constructs (four Chopart and one midfoot). One case of staple fatigue failure occurred at the bridge-leg interface.
conclusionNitinol compression staples provided reliable fixation for midfoot arthrodesis and acceptable outcomes in selected Chopart arthrodesis. Region-specific differences in union and failure patterns highlight the importance of construct planning and selective adjunct fixation for higher-risk Chopart constructs.
