Descriptive statistics for the overall, between, and within variation of forecasts, forecast errors and number of non-responses (i.e., attrition) are reported in Table 1.
A flow diagram of the study and further details of non-response and attrition are reported elsewhere.
In Uganda, similar attrition rates were reported among patients in the community- and clinic-based model [ 28].
We stated whether attrition and exclusions were reported, the numbers included in the analysis at each stage (compared with the total randomised participants), reasons for attrition or exclusion where reported, and whether missing data were balanced across groups or were related to outcomes.

The authors define inclusion criteria; The authors define an adequate selection method (for instance, all hospitalized patients with infection); The selection of participants was consecutive; The outcome data was complete (microbiology data by place of acquisition) and reported (no attrition bias); All results were reported (reporting bias).
Attrition rates ranging from 5%to50%0% were reported (see Table 4), yet not taken into account in the reported recovery rates.
More so that the thrust of the European studies support the view that erosion (resulting from acidic and carbonated foods and beverages) is more important than attrition in the aetiology of tooth wear [ 23], whereas, attrition have been reported to be more important than erosion in the aetiology of tooth wear among Nigerians [ 24, 25].
High rates of attrition have been reported in randomized controlled trials of patients with severe psychiatric illness, including psychotic depression (MDpsy).
Recently, a moulded DLC tip designed based on atom by atom attrition mechanism was reported to give approximately four orders of magnitude improvement on wear compared to the carbon nanotube tip [24].
