Screw versus helical proximal femoral nail in the treatment of unstable trochanteric fractures in the elderly.
Article in Journal of clinical orthopaedics and trauma. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled 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.
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
purposeComparison of clinical, radiological and functional outcomes of screw proximal femoral nail (PFN) and helical PFN in management of unstable trochanteric fractures.
methodsThis prospective randomised comparative study included 60 patients with closed unstable intertrochanteric fractures (AO classification-A2.2-A2.3 & A3.1-A3.3). Patients were randomised to 2 treatment groups using simple random sampling method utilizing computer based randomisation. Screw PFN and helical PFN were used for internal fixation with 30 patients in each group.
resultsBoth groups were similar in respect of age, gender, fracture classification, quality of fracture reduction, duration of hospitalization, post-operative complications, residual/late deformity as well as functional assessment. However, mean duration of surgery was significantly lower (23.1%) in helical PFN group as compared to screw PFN group (43.32 ± 8.20 min vs. 35.20 ± 6.03 min, p < 0.001). Furthermore, mean blood loss was not significant in either of the study groups but it was significantly lesser (30.1%) in helical PFN group as compared to screw PFN group (77.80 ± 17.39 ml vs. 59.80 ± 14.96 ml, p < 0.001). Also, mean number of images taken was significantly lower (58.7%) in helical PFN group as compared to screw PFN group (29.52 ± 4.85 no vs. 18.60 ± 3.12 no, t = 9.47; p < 0.001).
conclusionBoth screw PFN and helical PFN are equally effective implants in internal fixation of unstable trochanteric fractures with no statistically significant difference (p > 0.05) in any of the outcome measures. However, helical PFN group fared marginally better in terms of operative time, blood loss and imaging required.
