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

introductionGenicular radiofrequency ablation (RFA) is a minimally invasive treatment for knee pain with variable outcomes reported. This study aimed to evaluate genicular RFA in reducing pain and identify predictors of treatment success.

methodsThis retrospective study included 34 patients who underwent genicular RFA between April 2022 and December 2023. Data on demographics, pre- and post-procedure pain levels, and clinical variables were collected through chart reviews and follow-up surveys. The primary outcome was pain reduction at postoperative follow up. Statistical analyses were conducted to identify predictors of pain outcomes.

resultsRFA led to pain reduction in 24 patients (71%), though only 9 (26%) achieved >50% relief according to IMMPACT criteria. The mean pre-procedure pain score was 7.1 ± 1.4, which decreased to 5.2 ± 2.0 post-procedure. Lower pre-procedure Numeric Rating Score (NRS) was the strongest predictor of success (P < 0.001), while age, BMI, gender, and arthritis severity did not significantly impact outcomes.

conclusionWhile genicular RFA led to pain reduction in a majority of patients, only a subset experienced clinically significant improvement. Pre-procedure pain score was a key predictor of outcomes, suggesting the need for more refined patient selection criteria and further research into optimizing treatment targets.
