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

backgroundSubmuscular augmentation mastopexy (AM) is often recommended to improve stability and reduce implant visibility despite the risk of breast animation. Objective systems to measure this outcome are restricted by a lack of quantitative data.

objectivesThis analysis of animation investigates factors that influence outcomes of this procedure using the inferior pectoralis muscle flap technique.

methodsQuantitative data on breast animation, nipple (ND) displacement and inframammary fold (IMFD) displacement, nipple displacement angle, and lower pole contour distortion with the pectoralis muscle both relaxed and contracted were collected after AM with pectoralis muscle flap; animation was clinically assessed using a 4-point scale.

results134 patients (268 breasts) with a mean follow-up of 28.5 months (range, 6-72 months) were analyzed:60 patients underwent primary procedures. Mean values for ND and IMFD fold were 1.51cm (range:0.35-3.72cm) and 1.49cm (0.35-2.99cm), respectively. Patients undergoing secondary surgeries exhibited higher values for ND (1.98cm; 0.48-3.72cm, p<0.001) and IMFD (1.94 cm; 0.58-2.99cm, p=0.8) and more frequent grade II (p=0.027) and III (p=0.012) lower pole contour deformities than those subjected to primary procedures. Multivariate analysis found age>30 years (p<0.001) and BMI>18 (p<0.001) to be significantly associated with ND. Twelve patients (8.7%) underwent revision surgery; animation deformities (2.9%) and capsular contracture (2.2%) were the most frequent reasons for reoperation.

conclusionsThis study offers the first quantitative evaluation of animation deformities in AM patients and describes an objective method that provides data on muscular dynamics and breast distortion. Our experience shows that pectoralis muscle flap technique may successfully prevent and treat ptosis and implant malposition, but patients undergoing secondary AM have a higher risk of animation.
