Most Important Biostatatistics topics frequently asked in MRCP part 1

Imp Topics for Biostatistics :-

When you prepare for MRCP it seems time is evaporating as water evaporates from lake in the summer season.

It's very crucial to channelize your effort in most efficient way and there comes studying smartly.

Remember you won't have more than 5 or 6 questions from Biostatistics and majority of questions are asked from simple calculation based concepts such as

1. Sensitivity

2.Specificity

3.PPV

4.NPV

5.odds ratio

6.relative risk

And

7.significance of different stages of clinical trials 

8. Three sigma rule or 68-95-99.7

(68.27% of the values lie within one standard deviation of the mean. Similarly, 95.45% of the values lie within two standard deviations of the mean. Nearly all (99.73%) of the values lie within 3 SD)

I believe knowing only these formula will help you to fetch 70 to 80 % questions.

P.S.- while you are calculating a particular biostatistical parameter such as Sensitivity ,which is 

Basically  =TP/TP+FN 

It looks very simple and it is actually simple but what happens some times Royal college flips the value of TP,FP,FN in different / reverse order in the chart and then if you are not alert probably you will end up choosing wrong answer.

So first make sure which one is TP ,FP ,FN and TN.

Don't dwell too much in this subject coz no one gets right that 1 or 2 ultra difficult questions ,what matters is getting correct the remaining easily scoring biostat questions.
