Features of meta-analyses that compared polyethylene glycol to sodium phosphate
| Ref. | Period of inclusion | Comparisons | Trials, n1 | Patients, n1 | Results |
| Hsu and Imperiale[14] | 1980-1996 | PEG vs NaP | 8/8 | 1286/1286 | NaP better than PEG: |
| Better at cleansing | |||||
| Better at compliance | |||||
| Lower cost | |||||
| Safety: NaP = PEG | |||||
| Tan et al[15] | 1990-2005 | PEG/NaP/sodium picosulfate | 29/18 | 6459/3484 | NaP better than PEG: |
| Better at cleansing | |||||
| Better at compliance | |||||
| Safety: NaP = PEG | |||||
| Belsey et al[16] | Until January 2006 | PEG/NaP/Others | 82/25 | -/3748 | Cleansing: PEG = NaP |
| NaP better for tolerance | |||||
| Safety: PEG = NaP | |||||
| Juluri et al[17] | 1990-2008 | PEG vs NaP | 18/18 | 2792/2792 | NaP better than PEG: |
| Better at cleansing | |||||
| Better at compliance | |||||
| Safety: NaP = PEG | |||||
| Juluri et al[18] | 1990-2008 | PEG vs NaP | 71/71 | 10201/10201 | Not statistically different |
| NaP more likely to comply better | |||||
| Belsey et al[19] | Until June 2010 | PEG/NaP/others | 104/31 | -/4450 | PEG = NaP |
| PEG better than NaP in proximal colon | |||||
| No information about compliance |
