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

introductionThis study aimed to estimate separately in women and men the number of Total knee arthroplasty (TKA) procedures performed in Italy from 2001 to 2016, exploring specific gender-related characteristics and trends. MATERIALS AND

methodsData of this study were collected from the National Hospital Discharge Reports (NHDR) reported at the Italian Ministry of Health in the years between 2001 and 2016. The information included in this archive are the patient's sex, age, the year when the surgical procedure was performed and the length of the hospitalization.

resultsBetween the years 2001 and 2016, a total of 848,863 TKAs have been performed in Italy. TKAs in women passed from 20,719 in 2001 to 49,320 in 2016 showing an increase of 138%, while TKAs in men passed from 6631 in 2001 to 23,601 in 2016 showing an increase of 256%. From the age of 50 onwards, there was a prevalence of procedures in women, from 63.2% in the 50-54 group to 85.7% in the 100 + group. Conversely, under the age of 50, there was a higher percentage of surgeries performed in males, 57.1% on a total of 16,434 TKA surgeries carried out in this age group.

conclusionsThis study showed that TKA is growing and heavily affecting the female population (70.6% of all TKAs) between 2001 and 2016. However, under 50 years old there was a higher percentage of surgeries performed in males (57.1%). The average number of days of hospitalization in females was higher than in males.
