The main relevant features and outputs of the study were extracted for the purpose of 150 this systematic review and are summed up in Table 1 .
The included study was conducted between 2008 and 2009 in Denmark, over 12 152 months. It involved 404 general practitioners (GPs) participants and a total of 8236 contacts.
It included patients aged 40 years or more, grouped as those without any chronic condition 154 and those with one, two, three or more chronic conditions.
During the study period, the GPs completed a one-page registration form for each of 156 their patient contacts. Of the various items that were registered, the ones relevant forthis 157 review were information on chronic diseases and length-time of consultation. Quality 158 assessment result, performed as described in methodology, is presented in Table 2 . The 159 quality of the study was considered satisfactory (score 6 out of a maximum score of 10), its CC-BY-NC-ND 4.0 International license It is made available under a author/funder, who has granted medRxiv a license to display the preprint in perpetuity.

The present systematic review sought to answer the following question: "Is the average 
The data analysis must be evaluated using objective validated laboratory methods 243 and, if possible, it should be a blind assessment. Statistical tests used to analyse the data 244 must be appropriate and clearly described. Measures of association, including confidence 245 intervals and the P value, must be presented.
The main limitation of this systematic review was the difficulty in ensuring that all the 247 relevant literature was included. Even though the research used two of the main databases -
Pubmed and Embasethere could be other relevant material in grey literature.
The scarcity of the literature that was found was a limitation for this review. The one 
This "impact of MM on the duration of a consultation" has hardly been studied, this 259 systematic review shows.
A tendency for consultations of patients with MM to take longer than those without MM 261 was found in the only one study with "satisfactory" quality which met the inclusion criteria.
