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.
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
purposeProximal humerus fractures account for 4-5% of all fractures in adults and affect females more than males. With the advent of special locking plates, the treatment trend has shifted more towards a surgical approach. These methods have produced good results but very high complications rates have been reported in the literature. This study was undertaken to analyse the radiological parameters which reflect towards a favourable long term functional outcome in order to advance the surgical fixation skills for managing fractures of the proximal part of the humerus. MATERIALS AND
methods83 study participants with proximal humerus fracture fixed using proximal humerus locking plates were retrospectively analysed. The radiological parameters studied were neck shaft angle, head shaft angle, head diameter, head height, greater tuberosity to articular surface distance and reduction of the medial hinge with or without placement of calcar screw. The functional parameters assessed were the Constant Murley Score and range of movements of the shoulder joint. The patients were not followed further for the purpose of the study.
resultsThe mean Constant Murley Score for the participants was 80.75 ± 8.09 (range 60-90). The participants with good to excellent CM Score had a significantly higher neck shaft angle (107.47 ± 9.74 v/s 124.16 ± 10.68) and (-0.28 ± 0.85 v/s 2.37 ± 2.28), head shaft angle (23.09 ± 4.82 v/s 31.76 ± 7.76), head diameter (40.08 ± 8.63 v/s 45.15 ± 4.73), head height (18.77 ± 1.96 v/s 20.69 ± 2.76) and greater tuberosity to articular surface distance (-0.28±0.85 v/s 2.37±2.28) as compared to the patients with satisfactory and worse CM Score. The patients with a higher neck shaft angle and a maintained subacromial space had a better range of shoulder abduction. A higher rate of valgus collapse was seen with an inadequate medial hinge reduction.
conclusionThe radiological parameters which can predict towards a good functional outcome are a higher neck shaft angle and head shaft angle, a larger head diameter and head height, a superior position of the greater tuberosity in relation to the articular surface and a good medial hinge reduction.
