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

objectiveTo evaluate the effectiveness of interfragmentary compression in feline femoral transverse fractures treated with a dynamic compression angle-stable interlocking nail implanted via minimally invasive nail osteosynthesis.

methodsThirty femurs from 15 feline cadavers were allocated into three groups according to fracture location (n = 10 per group): proximal (GPD), mid- (GMD) and distal diaphysis (GDD). Radiographic and computed tomography scans were performed preoperatively for surgical planning and measurement of the anatomical lateral distal femoral angle, anatomical lateral proximal femoral angle and femoral torsion angle. Standardised transverse osteotomies were created per group allocation and stabilised using dynamic compression angle-stable interlocking nail implanted via minimally invasive nail osteosynthesis technique. Postoperative imaging assessed residual fracture gap and femoral angles. Data were analysed using one-way ANOVA with Tukey's post hoc test, and effect sizes were estimated using generalised eta squared (ges).

resultsAll groups achieved effective interfragmentary compression, with residual fracture gaps <1 mm (range: 0 to 0.3 mm). The anatomical lateral distal femoral angle remained consistent before and after osteosynthesis. The anatomical lateral proximal femoral angle remained unchanged in proximal diaphysis and distal diaphysis but showed a moderate increase in mid-diaphysis (ges = .445). The femoral torsion angle increased in all groups postoperatively, with large, moderate and small effect sizes in proximal diaphysis (ges = .655), mid-diaphysis (ges = .385) and distal diaphysis (ges = .213), respectively. CLINICAL SIGNIFICANCE: Dynamic compression angle-stable interlocking nail provided consistent interfragmentary compression. However, deviations in the transverse plane were observed following the minimally invasive nail osteosynthesis approach. These findings support dynamic compression angle-stable interlocking nail as a promising option for stabilising femoral transverse fractures in cats.
