Table 2. Weighted mean difference and 95% confidence intervals of three treatment modalities of clavicular fractures patients in terms of the Constant-Murley Score after 6 months.

WMD (95% CI)
Non-operative treatment	4.70 (1.21, 7.83)	6.71 (3.20, 10.39)
−4.70 (−7.83, −1.21)	Plate fixation	2.05 (0.30, 4.64)
−6.71 (−10.39, −3.20)	−2.05 (−4.64, −0.30)	Intramedullary pin fixation

Notes: Comparison between treatments should be read from column to row. WMD, weighted mean difference; 95% CI, 95%confidence intervals.
