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
Medial opening wedge high tibial osteotomy is a successful procedure for correction of varus malalignment in isolation or in combination with other knee ligamentous and cartilage procedures. This article describes a technique for medial opening wedge high tibial osteotomy using a Hintermann distractor, which allows better control of the osteotomy gap opening and the posterior tibial slope. Preoperative digital planning is undertaken. A small longitudinal incision and a minimally invasive approach are performed to expose the proximal tibia. The Hintermann distractor is applied over 2 guide wires inserted divergently proximal and distal to the transverse osteotomy. The Hintermann distractor is used to open the osteotomy gap and maintain or change the posterior tibial slope according to the preoperative plan. Unimpeded access is provided, with no instrumentation in the gap, and this allows precise positioning of an allograft bone wedge, which is followed by fixation with an angular stable locking plate. In this technique, the Hintermann distractor serves as an outrigger that provides support to the osteotomy and offers rotational control to change the posterior tibial slope if desired.
