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

backgroundDifferent minimally invasive approaches have been established in the management of elective hip arthroplasty. However, there is almost no data on the endoprosthetic treatment of femoral neck fractures in obese patients. MATERIALS AND

methodsThe monocentric case-control study is based on the retrospective evaluation of a database. Included were patients with a body mass index (BMI) of > 30 kg/m

resultsA total of 155 surgeries conducted between 2011 and 2024 were included, of which 52 procedures were performed using a DL approach and 103 procedures using an MIV AL approach. The mean age of the overall cohort was 77.9 ± 9.4 years, and the mean BMI was 33.4 ± 3.2 kg/m

conclusionThe MIV AL approach to endoprosthetic treatment of femoral neck fractures in obese patients showed a higher, but not significant, dislocation and infection rate compared to the DL approach. For the overall cohort, mortality rates were low. Recording the surgical approaches and BMI in registry data would be useful to generate larger case numbers. LEVEL OF EVIDENCE: III; retrospective case-control study.
