1 · What the graph read from it

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.

2 · The registry

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

This retrospective cohort study investigated whether low preoperative hemoglobin levels increase postoperative atrial fibrillation and flutter (POAF) risk following elective total joint arthroplasty. Using the TriNetX Analytics Network Platform, we analyzed patients aged ≥ 40 years undergoing primary knee or hip arthroplasty under general anesthesia between 2010 and 2024. Patients were categorized into low hemoglobin (8-12 g/dL) and control (> 12 g/dL) groups. After 1:1 propensity score matching yielded 22,996 pairs, Cox regression analysis revealed significantly higher six-month POAF incidence in the low hemoglobin group (1.4% vs. 0.97%; HR 1.39, 95% CI 1.17-1.65, p < 0.001). The low hemoglobin group also demonstrated increased all-cause mortality (1.0% vs. 0.47%; HR 2.10, p < 0.001) and ICU admissions (1.4% vs. 0.84%; HR 1.65, p < 0.001). Even mild hemoglobin reduction (10-12 g/dL) significantly elevated POAF risk (HR 1.35, p = 0.001). Temporal analysis showed peak POAF risk occurring 30-180 days postoperatively, with effects persisting up to three years. These findings establish low preoperative hemoglobin as an independent, clinically significant risk factor for POAF and adverse outcomes following orthopedic surgery, suggesting preoperative anemia correction may be a valuable intervention for improving postoperative outcomes.
