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

purposeFor calcaneal fracture, plate fixation through lateral extensive approach (LEP) is the most common procedure performed to achieve anatomic reduction. However, wound complications sometimes occur after LEP. To reduce complications, minimally invasive operative methods with cannulated screw fixation through sinus tarsi approach (STS) were developed. The aim of this multicenter propensity-matched study was to compare the clinical and radiographic outcomes of LEP to those of STS for calcaneal fracture and to evaluate the incidence of postoperative complications including surgical site infection (SSI).

methodsWe extracted 271 patients with calcaneal fracture undergoing surgery between January 2014 and March 2019 from our multicenter TRON database. We assessed the American Orthopedic Foot and Ankle Society (AOFAS) score at the final follow-up as the clinical outcome. We obtained the Bohler and Preis angles as radiographic parameters and also recorded the complications. We divided the subjects into two groups: LEP group and STS group. To adjust for baseline differences between the groups, a propensity score matching algorithm was used in a 1:1 ratio.

resultsAfter matching, there were 32 fractures in each group. There was no significant difference between the LEP versus STS group in AOFAS score at final follow-up (90 vs 90 points, p = 0.98) and in the Bohler and Pries angles (19.2 vs. 18.0 degrees, p = 0.74 and 16.0 vs. 17.5 degrees, p = 0.47). The rate of SSI in the LEP group was higher than that in the STS group (21.9% vs. 0.0%, p = 0.01).

conclusionFor calcaneal fracture, STS provides similar fixation effectiveness and functional outcomes as LEP while reducing the likelihood of infection.
