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 compare the predictive value of the two concepts for complications by comparing the incidences of surgical complications associated with different tip-apex distance (TAD) and calcar referenced tip-apex distance (Cal-TAD) in the treatment of femoral intertrochanteric fractures with Asian type proximal femoral nail (APFN) fixation.

methodsA total of 188 cases of femoral intertrochanteric fractures treated with APFN fixation between January 2014 and December 2018 were collected according to inclusion criteria. TAD and Cal-TAD were measured on the X-ray film at immediate after operation; the patients were divided into two groups according to the measurement results: <25 mm and ≥25 mm. Gender, age, and fracture side and AO type were recorded. The patients in each group were reviewed whether there was delayed fracture union or nonunion, whether the screw blade moved axially, whether the femoral neck collapsed or even screw blade cut out, whether the internal fixator became loose or broken within 12 months after operation. Then statistical analysis was performed.

resultsThere were 119 patients with TAD<25 mm and 69 patients with TAD≥25 mm, and 142 patients with Cal-TAD<25 mm and 46 patients with Cal-TAD≥25 mm. There was no significant difference in gender, age, or fracture side and AO type between groups (

conclusionIn the operation of femoral intertrochanteric fracture with APFN fixation, surgical complications can be significantly reduced when TAD or Cal-TAD was controlled within 25 mm, Cal-TAD is more significant in the prediction of postoperative complications.
