In fact, when pooling the donor-site morbidity rates reported in the literature, the figures range substantially from 0 to 92 % and 0 to 55 %, with calculated pooled rates of 5.9 and 19.6 % for the knee and ankle joint, respectively.
A potential correlation might have been cloaked by the wide range of donor-site morbidity rates reported among the studies, different surgical techniques, chosen donor-site for harvesting and small sample sizes.
The two RCTs that did include dichotomous outcomes in terms of disease and morbidity rates reported a negative Berger-Exner test at alpha level 5% and employed varying block randomisation [ 15] and fixed block randomisation with block size 8 [ 16].
In the same study, the highest morbidity rate was reported for goats, with 77% of goats in Garissa and Ijara districts reported to have fallen sick during this period.
Forceps have long been associated with birth trauma, particularly when used for rotational procedures, but low overall morbidity rates are reported for well-trained forceps practitioners [ 7].
Three month morbidity and mortality rates reported from studies or reviews of similar approaches but without BEV, ranged from 23 to 31 %, and from 3to4%4 %, respectively.
An ASCO review of the recent literature shows that RFA has a mortality of 0 2% and the most commonly reported morbidity rate is 6 9%, with a low major complication rate.
Crude population morbidity rates are initially reported for each time period.
A second limitation is the fact that long-term effects of CRT on mortality and/or morbidity rates were not reported in the current study as the patient population was too small for long-term outcome analysis.
Radiofrequency ablation of lung tumours is a relatively safe procedure, with low mortality (around 0.4%) and excellent tolerance in terms of respiratory function, although the reported periprocedural morbidity rate ranges from 15.5% to 55.6% (median 35.7%), with an 8 12% major complication rate [20].
