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
purposeFemoral neck fractures in older adults are commonly treated with hip hemiarthroplasty (HA). Many older adults who sustain femoral neck fractures are also receiving long-term anticoagulation therapy, which may negatively affect patient outcomes after HA. We sought to investigate whether long-term anticoagulation therapy is associated with increased risks of surgical wound complications among older adults treated with HA for femoral neck fracture.
methodsPatients ≥ 60 years old who underwent HA within two days of admission for femoral neck fracture between October 1, 2015-December 31, 2021 were identified using codes in the Premier Healthcare Database. Long-term anticoagulation therapy was defined as an active prescription of anticoagulant medication at time of admission. A propensity score for the probability of long-term anticoagulant therapy was used to match patients. The adjusted odds of 90-day infectious surgical wound complications (deep and superficial) and non-infectious surgical wound complications (wound dehiscence, seroma, or hematoma) were determined from the matched patients.
results7218 patients on long-term anticoagulation therapy were matched to 7218 patients with no history of anticoagulation therapy. Patients with a history of long-term anticoagulation therapy experienced higher unadjusted rates of non-infectious surgical wound complications (2.15% vs. 1.29%, p < 0.001). No difference in the incidence of surgical site infection was observed between groups (1.73% vs. 1.30%, p = 0.111). After propensity score matching, patients on long-term anticoagulation therapy had higher odds of non-infectious (adjusted odds ratio [aOR]: 1.65, 95% confidence interval [CI] 1.27-2.15, p < 0.001) and infectious (aOR: 1.38, CI 1.05-1.81, p = 0.021) surgical wound complications.
conclusionLong-term anticoagulation therapy confers an independent risk of wound complications among older adults undergoing HA for femoral neck fracture.
