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

purposeThis study examines the efficacy of genicular artery embolization (GAE) as a treatment to reduce chronic knee pain in patients who have previously undergone total knee arthroplasty (TKA). MATERIALS AND

methodsThirty-seven consecutive patients (13 men and 24 women) with a history of persistent pain for at least one year after TKA underwent GAE at a single center. The mean age across all patients was 72.8 ± 9.7 years, and the mean BMI was 29.3 ± 6.1 kg/m

resultsAmong 37 patients, WOMAC scores at the preliminary, one-month, and three-month follow-up appointments were 64% ± 6%, 39% ± 8%, and 36% ± 8%, respectively (95% CI). VAS scores were 8.1 ± 0.6, 3.2 ± 1.1, and 3.1 ± 1.0 (95% CI). A paired t-test showed a statistically significant improvement at both one-month and three-month post-procedure evaluations. (p < 0.05). Overall, 64.9% (n = 24) of patients achieved at least a 50% improvement in pain scores by the end of the study term.

conclusionGAE shows efficacy as an adjunct treatment in patients with TKA and long-standing pain (> 1 year). Further research is needed to assess long-term outcomes and broader applicability.
