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
objectiveThis study aimed to compare clinical outcomes and total treatment costs of 3 fixation strategies-isolated dorsal plating, dorsal plating with a single lag screw, and dorsal plating with dual lag screws-in patients undergoing first metatarsophalangeal (MTP) joint arthrodesis for advanced hallux rigidus. Methods: This retrospective study included 99 patients who underwent primary first MTP joint arthrodesis between 2019 and 2024. Patients were categorized into Group 1 (dorsal plate only; n = 27), Group 2 (plate + 1 lag screw; n = 42), and Group 3 (plate + 2 lag screws; n = 30). Demographic variables, radiographic union, revision rates, functional outcomes (American Orthopaedic Foot and Ankle Society [AOFAS], Visual Analog Scale [VAS], Foot Function Index [FFI]), and total 12-month treatment costs were evaluated. The primary outcome measures were union rate, time to union, revision surgery, functional scores, and cumulative cost. Results: Group 1 demonstrated significantly lower union rates compared with Groups 2 and 3 (88.9% vs. 100% for both; P = .027) and a longer mean time to union (75 days vs. 65.8 and 62 days, respectively; P = .001). Revision surgery was required only in Group 1 (11.1%). The AOFAS scores were significantly higher in the screw-augmented groups (P = .013), while VAS and FFI scores showed no between-group differences. Cost analysis identified Group 2 as the most cost-effective strategy (9500 ± 1100 TL ≈ $310 ± 36), compared with Group 1 (11 200 ± 1400 TL ≈ $365 ± 46, P = .021) and Group 3 (11 600 ± 1300 TL ≈ $378 ± 42, P = .038). Conclusion: Single lag-screw augmentation of dorsal plate fixation provides superior union, fewer revisions, improved functional scores, and the lowest overall 12-month cost. These findings support dorsal plating with a single lag screw as a practical, value-based fixation strategy for advanced hallux rigidus, offering optimal clinical and economic outcomes.
