Outcomes of Temporary Hemi-Epiphysiodesis Using a New Device for The Treatment of Pediatric Valgus Knee Deformity: a Preliminary Report.
Article in The archives of bone and joint surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aimed to evaluate the efficacy of hemi-epiphysiodesis using a new device (X-plate) for the correction of genu valgum.
methodsIn total, 22 children with a total of 34 pathologic knee valgus deformities underwent the procedure and were followed up 25.3 months on average.
resultsThe mean time to clinical correction of genu valgum was 10.9±2.2 months. Furthermore, the mean preoperative anatomic Lateral Distal Femoral Angle (aLDFA) and mechanical Tibia Femoral angle (mTFA) were obtained at 75.1±3.8 and 6±2.8 degrees, respectively. When clinical correction of the deformity was achieved, the mean of aLDFA and mTFA corrections were determined at 8.9±5.3 and 6.5±3.2 degrees, respectively. The mean speed of aLDFA and mTFA corrections were estimated at 0.8±0.45 and 0.6±0.3 degrees per month, respectively. The postoperative aLDFA and mTFA were measured at 84±4.2 and -0.8±2.9 on average. With a mean of 25.3±14.5 months at final follow-up, there were 6 (17.6%) mild valgus knees, 26 (75.5%) normal alignment knees, and only 2 (5.9%) mild varus knee within an acceptable clinical limit.
conclusionHemi-epiphysiodesis using X-plate at the distal physis of the femur is an effective and safe method for the treatment of valgus knee deformity in children.
