The reporting timeframe differed among studies.
During this timeframe, the differences relating to the number of doctor consultations were relatively low.
Conclusions Applying different mortality timeframes resulted in differences in standardised mortality ratios and differences in judgment regarding the performance of individual hospitals.
Further subgroup analyses revealed pain severity and interference to be highest among patients prescribed antivirals within 72 hours of rash, compared to those not prescribed antivirals within this timeframe (although only differences for pain interference were statistically significant).
As suggested, polytomies might be quite common in microbial taxonomy trees since many times evolutionary relationships of interested species cannot be fully resolved to separate descending branches or difference of timeframes between two divergences.
Focusing on Spain, the baseline evaluation indicated that our FM patients from Aragon produced higher healthcare costs (1,940€) and sick-leave costs (810€), on average, than those reported by Sicras-Mainar et al. [ 46] in Catalonia (healthcare costs = 1,677€ and sick-leave costs = 815.8€); of note is the difference in timeframes (6-month period versus 12-month period).
Early anchor: differences between baseline and 2nd week follow up, and 2. Late anchor: differences between 2nd week and 4th week follow up), we were able to estimate MID using two anchors with different timeframe.
Compared with standardised mortality ratios based on in-hospital mortality, we found that these timeframes resulted in differences in ratios and even altered judgments regarding the performance of individual hospitals.
During the study timeframe the range in the difference between average daily high and low humidex was 14.03 to 28.71 °C, with the difference increasing as average daily maximum humidex increased.
As to the effect of using different timeframes in the studies, there was little difference between the migraine prevalence in those studies in which the timeframe was not stated [9, 51] compared to the studies asking about headache during the last year [10 , 15 36, 37, 40 42, 49, 57] (12.9 vs. 13.0%).
