Open WellbeingWhat the studies actually measured

Joints, muscles and pain

Boswellia serrataand Morning Stiffness Duration

Both sources here measured lower morning Stiffness Duration.

How sure anyone can be

Low certainty, level 2 of 4

Further research is likely to change this.

The most certain of the two findings here; each record carries its own.

The numbers reported

One source’s range, drawn against its own line of no difference and scaled to its own numbers.

-15.86-10.04-4.22

This range stays on one side of the no-difference line.

Two sources, newest first

What we read is the published abstract, not the full paper, so a blank below may still be printed in the paper itself. A fixed rule worked this out from the source’s own fields. Nobody checked this rating by hand.

    AI review could not confirm it — an AI agent re-read this finding against the saved source and at least one check failed. The batch record names the check and quotes the sentence that caused the doubt. No person read it.

What is still missing from these readings

  • One gives no likely range, so how precise that number is is unknown.
  • Two do not say how many people took part.
  • Amount taken — Not in the abstract.
  • For how long — Not in the abstract.

Something nobody wrote down is never a zero and never a guess.

Still to read for Boswellia serrata

Eight of the 13 things on our list for Boswellia serrata have no reading here yet:

  • Alanine aminotransferase (ALT)
  • Equivalent Walking Distance
  • Erythrocyte Sedimentation Rate (ESR)
  • Forced Vital Capacity (FVC)
  • Hemoglobin
  • Peak Expiratory Flow Rate
  • Physical Function Score (SF-36 Physical Functioning)
  • Serum creatinine

Still to read means nobody here has got to it, not that it was tried and did nothing or that no research exists. A pairing on no list is not a gap: we never set out to read it.
