All results support the assumption of a miss-allocation of students to lower secondary school tracks.
A last observed carried forward strategy was used, and sensitivity analysis was carried out by comparing with results based on two other missing data allocation techniques (summary statistics and mixed model analysis).
We tested stability of the results using all trials, excluding and including debatable trials, by comparing the results of full intention to treat with restricted intention to treat and per protocol analysis and by comparing the last observation carried forward with missing data allocation based on summary statistics.
Recruitment numbers, reasons for not being eligible or enrolled as well as allocation, missing data and reasons for missing data are reported in the CONSORT flow diagram.
Fig. 12 Allocation missing ratio with different prediction error ratio.
"APR" or "variable interest rate" define how your rate will change over time or if you miss a payment; "payment allocation" means how your payments will change if your rate is altered.
5 of the authors replied to queries regarding missing information on randomization, allocation, and baseline group similarities.
Then, the percentage of the allocation failure, called missing ratio, is measured for the "static allocation" and "static allocation with the dynamic phase".
The Cochrane RoB tool evaluates six domains including: sequence generation, allocation concealment, blinding, missing outcome data, selective outcome reporting, and "other sources of bias".
However, because the missing data were assumed to be missing at random, systematic bias between treatment allocation and potential effect modifiers was unlikely.
They contain the 'rules' for derivations of variables, defining/coding variables, range limits, and allocation to refusal and missing values.
