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
introductionHand rejuvenation treatment is in high demand in cosmetic medicine. Radiesse®, a commercially available formulation of calcium hydroxylapatite (CaHA), is safe, biocompatible, and provides long-lasting results.
objectiveThe study aimed to retrospectively evaluate the efficacy and safety of the presented formulation of Radiesse® and its injection procedure.
methodsThe hands of 58 women were treated employing Radiesse® diluted with lidocaine. The treatment was performed using a blunt cannula following the proximal-to-distal fanning technique at two entry points on the dorsum of the hands. The patients received 1-4 treatments over a follow-up period of up to five years.
resultsThe hands of 58 females were evaluated using the Merz Hand Grading Scale (MHGS) and treated with the presented CaHA formulation. After the first treatment, 55 patients (94.8%) achieved a 1-point improvement, and 19 patients (32.8%) did not receive further treatment, being satisfied with the results. The remaining 39 women (67.2%) received 2-4 follow-up treatments. At the end of the treatment(s), 46 women (79%) achieved a final improvement of one point, and 12 women (21%) a final improvement of two points. Three minor adverse events were registered.
conclusionsRadiesse® diluted with lidocaine is an excellent choice for hand rejuvenation. The formulation and technique proved to be safe and efficient. In our experience, a blunt cannula should be employed for optimal vein correction. The treatment was highly satisfying, although planning a second treatment during the 1-month follow-up visit is recommended to best achieve long-lasting results.
