This is a great program. Easy to use and print and save to my computer. However, I would have liked the option to subscribe and pay by the month instead of an entire year at once.

Had similar capability on work computer(s)> I was fine with filling out PDF files and saving them. Ths allows signatures and other features that may get me to keep it.

Handy service. Swift support. I am amazed
Let me share with you my experience frankly. I needed to edit a one single pdf document. Found this service. Registered for a free trial. Edited the document swiftly and smoothly. And forgot about it. Till the moment I received a charge for the yearly subscription. Which, admittedly, is not low at all (though may be reasonable to those who use this service).Anyway, I contacted pdfFiller support team, and I was surprised by both: 1) the fact that they immediately agreed to issue a refund, as it met their policy (I canceled in less than 24 hours, actually, immediately) 2) that even though they told that I will receive the money back within 1-5 business days - I got it within a few minutes. I am perplexed. The only pity really is that I can't afford it

Great customer support
Great customer support. I forgot about a 30-day free trial period because I didn’t use the app after registering and checking it only once. They took the money for the whole year through PayPal and when I explained the situation they helped me with the cancellation of my subscription in a half an hour. They gave me the whole sum of money back.

How do you calculate age standardized?
To calculate the age-standardized mortality rate (ASMR), we must first calculate the age-specific (mortality) rates for each age group by dividing the number of deaths by the respective population, and then multiplying the resulting number by 100,000: Age-specific rate, 0 to 39 years.
What is age standardized rate?
An age-standardised rate (ASR) is a summary measure of the rate that a population would have if it had a standard age structure. Standardization is necessary when comparing several populations that differ with respect to age because age has a powerful influence on the risk of dying from cancer.
How do you calculate standardized risk ratio?
Standardized mortality ratio. The standardized mortality ratio is the ratio of observed deaths in the study group to expected deaths in the general population. This ratio can be expressed as a percentage simply by multiplying by 100. The SMR may be quoted as either a ratio or a percentage.
How do you calculate standardized mortality ratio?
Standardized mortality ratio. The standardized mortality ratio is the ratio of observed deaths in the study group to expected deaths in the general population. This ratio can be expressed as a percentage simply by multiplying by 100. The SMR may be quoted as either a ratio or a percentage.
What does standardize mortality ratio mean?
Standardized Mortality Ratio (SMR) is a ratio between the observed number of deaths in a study population and the number of deaths would be expected, based on the age- and sex-specific rates in a standard population and the population size of the study population by the same age/sex groups.
What is age standardized incidence rate?
Calculating age-standardized rates The age-standardized incidence rate is the summary rate that would have been observed, given the schedule of age-specific rates, in a population with the age composition of some reference population, often called the standard population.
How do you calculate age standardized prevalence?
Calculation of the Age-standardized Rate Age-specific rate, 0 to 39 years. = 1,345 (number of deaths) ÷ 17,068,876 (total population) A 100,000. = 7.9 cancer deaths per 100,000 population.
What is age adjusted rate?
The age-adjusted rates are rates that would have existed if the population under study had the same age distribution as the “standard” population. Therefore, they are summary measures adjusted for differences in age distributions.
