Our latest study led by Prof Louis Lau showed that post-ESD patients were not at a higher risk of metachronous advanced adenoma recurrence, potentially impacting future surveillance guidelines

Happy to share our #HK #FMT registry prospective data! We found that the adverse event profile and longterm safety outcomes were favourable! Ready for prime time? 💩🦠💊

Prophylactic clipping is indicated after removal of >2cm and right-sided colonic lesions.✂️ Will high-risk patients on anticoagulants benefit from this?💡

In our recent study @GIE_Journal, we found that it was not associated with a reduced risk of PPB.🩸

@SultanMahmoodMD @RashidLui @ShimaghavimiMD @GiJournal @Gut_BMJ @8pm @abdullahaabbasi @LouisHSLau Not an expert either 😆
IPTW uses weights based on propensity scores and creates a weighted population such that clinical features are balanced
As for PS, it reflects the probability of being in the intervention group
As for how good it is, we need our expert @TerryYip12

@abdullahaabbasi @SultanMahmoodMD @GiJournal @Gut_BMJ @8pm @ShimaghavimiMD @RashidLui @LouisHSLau The greatest concern here was whether the data was "missing not at random" (MNAR), which would imply that the missing data could have been associated the patient's condition, such as the severity of the bleeding. This would affect the validity of the imputation of data
