The morbidity with temporary disablement (MTD) was studied with the help of Pearson's [correction of Pirson's] criterion in 689 empiric rows. The effect of work conditions on such morbidity was scored by dispersion analysis, demanding to take into account not only intergroup parameters connected with work conditions, but also intragroup ones, depending on casual circumstances, that is why the results should be regarded as preliminary data. The estimated effect of work conditions on the MTD shows unjustified high results for the year, because intragroup parameters were levelled. |
