Registered outcomes 4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Change in cognitive function | At the baseline, after 6 months and through study completion, an average of 1 year | We measure the cognitive function of children by means of a battery of tests including: stroop test, Continuous Performance, digit span, digit signal and digit selection. We combine the computer tests with eye tracking to provide information about saccadic gain during the tests. The computer tests provide data on how much time per reaction (msec) was needed or how many digits could be remembered. | ClinicalTrials.gov |
| Primary | Change in wellbeing | at the baseline, after 6 months and through study completion, an average of 1 year | We measure the emotional wellbeing by means of the Kids screen test that builds a score of 27 points. | ClinicalTrials.gov |
| Primary | Change in anthropometry | at the baseline, after 6 months and through study completion, an average of 1 year | We measure BMI and waist/hip circumference. They are expressed as kg/m2 and cm. | ClinicalTrials.gov |
| Primary | Change in black carbon levels | at the baseline, after 6 months and through study completion, an average of 1 year | We measure urinary black carbon levels. They are expressed as particles per mm2. | ClinicalTrials.gov |
