Population were adults over 18 years. 26 studies were reviewed. No information on IRB approval | The evidence-based librarianship (EBL) Critical Appraisal checklist was used for analysis. The overall validity (global rating) of the studies was determined based on the “Yes” scores ≥75% or “No/Unclear” scores ≤25%.

Study included 9,965 adult patients. Purposive sampling. IRB of the Hospital District of Southwest Finland | Chi-squared test, mean, SD. A Cox proportional hazards model with mJ/C score. Both the mJ/C score (P=0.0002) and the type of first mattress (P<0.0001). | The incident of PUs among patients on MPAs was significantly lower than on any of the other mattresses. | Informs the effectiveness of MPAs on reducing PUs. |
| 8 | Sauvage et al. /2017/ Journal of Wound Care. | To compare Axtair One, an alternating pressure air mattress (APAM), with a viscoelastic foam mattress (VFM) in elderly patients at moderate to high risk of developing pressure ulcers (PUs). | Level II | RCTs | Dependent: Risk of PU
Independent: Axtair One, an alternating pressure air mattress (APAM), a viscoelastic foam mattress (VFM) |
Patients were aged 70 and over and 76 patients were included. Randomized sampling. IRB approved. | Percentages, A sequential test, 80% with an alpha risk of 5%, 95% confidence interval (CI). The cumulative risk of PUs was estimated at 6.46% [95% confidence interval (CI): 1.64; 23.66] in the APAM group and at 38.91% [95% CI: 24.66; 57.59] in the VFM group | The APAM was superior to a VFM for preventing PUs in elderly patients | Informs the efficacy of APAM compared to VFM. |

Population included about 100 people. 19 RCTs were reviewed. No IRB approval | RR with 95% CI, mean.
