Scaling annual person year event rate meta-analysis STATA

I am looking at how I can scale my person-year event rate to be expressed per 1000 person-years

I have scaled the event rate by 1000 but then I'm not sure how I can place this on a forest plot with pooled outcomes

I have tried setting this up using meta set - declaring a generic precomputed effect size and calculating the SE - sqrt events/follow up time^2 for this purpose but the CI is negative which is not consistent with the event nature

Any ideas?

APHA 2024 tickets

Hey everyone! I know it’s last minute, but does anyone by chance have a full pass or even a day pass for APHA 2024 in Minneapolis? I live here and just recently graduated, but I’m way too broke to afford it right now since I’m only an intern, lol. If anyone could bless me with a pass, I’d be super grateful. Let me know! 🤞🏾🤞🏾

Masters in Epidemology but focusing in mental disorders

I am currently finishing up my first semester of my Masters in general psych. I'm wanting to get a masters in epidemology when im done and focus on mental disorders. Im just not sure if I should finish this masters or just go ahead and switch programs. My bachelors is in psychology and I just want to make sure I'm not getting an extra masters without needing to.

Are the forest plot diamonds an arbitrary size?

I’m redoing a meta-analysis both for work and as part of a grad course. Had a chat with our RWE expert and that’s what he said.

I thought it actually meant something?

can I use the JBI critical appraisal checklist for analytical cross-sectional studies for cross-sectional studies other than analytical?

Hi All,
I'm new to research and I'd like to know which quality appraisal tool works for descriptive cross-sectional studies. there are none in CASPs and just for analytical cross-sectional studies in JBI. I'm doing a systematic review in which most of my studies are cross-sectional with some cohort. HELP me, please!

Actual Airborne Pathogens Versus Droplet-Carried

TLDR: Are droplet-transported viruses actually airborne?

I know a nurse and doctor who claim masks aren't effective at all against viruses like COVID19, which the nurse claims is "airborne." I remember reading an article about this stating C19 is not an airborne virus, which I'm under the impression can survive in the air for a fairly long period in varying temperatures.

As far as masks go, I'm also under the impression a simple cloth mask or face covering would catch and absorb at least some droplets of infected airborne droplets, and prevent inhalation. But I know something like a K95 mask is best for preventing reception.

Just wanted to ask the sub and hear your input.

Are there special reasons to fear H5N1 over other flu subtypes besides case severity?

If H5N1 achieves human-to-human transmission akin to other flus, but the strain(s) turn out to also be only about the same severity as other flu subtypes, then would there be any special cause for concern about H5N1, beyond what we should have for other flu subtypes?

EDIT: To be clear, by "severity" I specifically mean how unpleasant the symptoms are, or how likely death is, in an individual infected person.

Inf. disease Agent Based Model data sources?

I am working on a project to develop an AI schema that detects disease clusters from surveillance data. I can give more information if necessary, but my question relates to finding training data. We have a PhD student who is writing some agent based models that ultimately will be used for training the AI system, but I would like to know if anyone knows of published infectious disease ABMs that I may be able to use for training sooner than the student will finish. I am doing lit search, but I would like data at the level of individual agents, not populations. Thought I would toss it up here for any suggestions.

Data for analysis

I am finishing my masters in Epi and for my thesis I’ve been advised to analyze data that already exists rather than collect my own original data. I have worked with NHANES before but my current research is aimed towards cancer epi and pharmaceutical data. I am wondering if anyone knows of any free databases or cohort data that I can download and analyze in stats software. I am familiar with SEER data but haven’t dove into it yet

Mpox outbreak 2022 vs now

Hi, I had a debate on the simmilarities and differences of the mpox outbreak 2022 and now. Does someone have an educated guess, if we are currently at the beginning of the outbreak or will numbers go down soon?

How does this outbreak compare to 2022 in terms of severity?

Thank you!

PowerBI+Electronic Surveillance Systems

Hi all, Just reaching out in hopes that one of you may be able to guide me in the right direction. As a California Epi, we use CalREDIE as a disease surveillance and reporting system. Any idea how I’d be able to integrate CalREDIE and PowerBI without downloading/extracting data from the system and uploading it to PowerBI? Thank you fam!

How would a pandemic caused by a virus that primarily spreads through direct contact (ie monkeypox) would differ from a pandemic caused by a virus that’s primarily airborne (ie COVID or H5N1)?

Just curious, I don’t know what to say here.

Cox PH or IRR

I’m planning a study that looks at different treatments and their effect on TIA incidence. I know survival analyses provide time to event estimates whereas incidence rate is an overall estimate over number of person years. Can anyone explain to me why I would use incidence rate ratio over Cox PH in this case?
