b. 437-438

composition: Op. 11, Concerto in E minor, Mvt I

Slur in FE (→EE)

Slur in GE1 (→GE2)

Dots & slur in GE3

Slur suggested by the editors

..

In the main text, we suggest beginning the slur earlier than in the sources due to the slur in the L.H. and slurs in analogous bars 412-413. The earlier ending of the slur in GE1 (→GE2) is most probably inaccurate, whereas the staccato dots added in GE3 are an arbitrary revision.

b. 437

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE, there is no  raising d2 to d​​​​​​​before the 1st semiquaver. This patent inaccuracy was corrected in GE and EE.

b. 437-438

composition: Op. 11, Concerto in E minor, Mvt I

No marks in FE (→GE1GE2)

Wedges in EE

R.H. wedge in GE3

..

In this context, the missing staccato marks must be considered an inadvertence of Chopin or the engraver of FE, which was noticed already in EE and partially – only in the R.H. – also in GE3.

composition: Op. 39, Scherzo in C♯ minor

In FE before the chord there is natural on e2.

b. 438

composition: Op. 21, Concerto in F minor, Mvt III

..

In A there is no  returning c4. The harmonic context and a comparison with an identical figure four bars earlier prove Chopin's mistake. The sign was added already in GE (→FEEE).
