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

backgroundPertrochanteric fractures of the femur in the elderly are very common. As the average age of the population increases, the incidence of such fractures also raises, resulting in high healthcare costs. The type of surgical devices employed for their surgical management influences these costs.

methodsA comparative clinical study was conducted on patients operated by one single surgeon between December 2018 and November 2020 in a high-volume regional referral centre. All patients who received a Zimmer Natural Nail (ZNN) or ELOS devices were included.

resultsIn 119 (66.48%) of the 179 fractures, a ZNN nail was used. Post-operatively, the TAD (tip-to-apex distance) was measured at an average value of 17.05 (4.42-41.85) mm and the CalTAD (calcar-referenced TAD) at an average of 20.76 (10.82-43.63) mm. The mean hospitalization time was 10.19 (4-22) days. In the other 60 trochanteric fractures, an ELOS nail was used. Post-operative imaging indicated a TAD of 19.65 (5.08-31.4) mm and a CalTAD of 22.86 mm (12.66-33.77). The average time of the operation was 45.82 (20-110) min. The average period of hospitalization was 10.45 (5-24) days.

conclusionBoth devices give similar results in terms of short-term post-operative outcome and hospitalization. The price difference between the devices does not translate in different short-term results on the operated patients.
