The median number of participants per trial in the sample of 258 reviews was 118 (interquartilerange, 60 to 241). The number of databases searched per review ranged between 1 and 27 (mean, 5.5; median, 4; interquartilerange from 3 to 6). Most outcome scores were non-normally distributed therefore outcome measures were described in median scores, including interquartilerange. Most participants reported having injected drugs for many years (median 17 years, range 1-51, interquartilerange 9-25). The finding is substantively identical if one substitutes the median and interquartilerange for the mean score plus or minus one standard deviation. The median age was 31 years (interquartilerange 27-34 years). The total number of sources used per review ranged between 2 and 30 (mean 8, median 6; interquartilerange from 5 to 9). This narrower interquartilerange gives the variable model its advantage over the fixed model. Of the remainder who did have symptomatic recurrences, the median number of recurrences was 2 per year (interquartilerange 1+9). The median number of participants per review was 945 (interquartilerange, 313 to 2,511). We note here that the median duration was 28 weeks (interquartilerange, 9-52 weeks). For each subsidiary outcome variable, the median and interquartilerange were calculated at 3 months. The whiskers give 1.5 times the interquartilerange. The interim advisory committee's recommendations fall exactly within the interquartilerange and were deliberately made to do so. From the Hansard archive Example from the Hansard archive.
