1. Error in Table Legend

In the original publication [1], there was a mistake in the legend for Table 3. The wrong term “PFS” was used instead of the right term “DFS”. The correct legend appears below.

Table 3. Univariate analysis for OS, EFS, and DFS of several risk factors.

2. Error in Table

In the original publication, there was a mistake in Table 3. The wrong term “time to progression (TTP)” was used instead of the right term “Disease-free survival (DFS)”. The corrected Table 3 appears below.

3. Error in Figure Legend

In the original publication, there was a mistake in the legend for Figure 3. The wrong term “time to progression (TTP)” was used instead of the right term “Disease-free survival (DFS)”. The correct legend appears below.

Figure 3. (A) Overall survival (OS) estimated at 24 months is 54%; (B) disease-free survival estimated at 24 months is 74%. The dotted black lines represent the 95% Confidence Intervals. Dots on survival curves are the events.

4. Error in Figure

In the original publication, there was a mistake in Figure 3. The wrong term “time to progression (TTP)” was used instead of the right term “Disease-free survival (DFS)”. No changes to the figure data have been made. The corrected Figure 3 appears below.

Figure 3.

(A) Overall survival (OS) estimated at 24 months is 54%; (B) disease-free survival estimated at 24 months is 74%. The dotted black lines represent the 95% Confidence Intervals. Dots on survival curves are the events.

5. Text Correction

There was an error in the original publication. The wrong term “time to progression (TTP)” was used instead of the right term “Disease-free survival (DFS)” in some sections of the manuscript and the abstract. Also, a typo regarding the CI has been corrected.

A correction has been made to the Abstract section:

At the end of induction, 14/22 (64%) achieved complete remission; overall survival and event-free survival at 24 months were both 54% (95% CI = 32–72%), while the disease-free survival was 74% (95% CI = 48–88%).

A correction has been made to Results, In Vitro results:

Simultaneous exposure to metronomic VNR and ETO showed synergism (CI < 1) at effect levels exceeding 60% inhibition represented by the fraction of affected cells (Figure 1B). Synergism corresponding to CI < 1 always yielded a favourable DRI for both drugs (Table 1).

A correction has been made to Results, Clinical results:

Overall (OS) (Figure 3A) and event-free (EFS) survivals at 24 months were both 54% 95% CI = 32–72), while disease-free survival (DFS) was 74% (95% CI = 48–88%) (Figure 3B).

A correction has been made to Discussion:

In this series, the higher value of DFS versus OS reflects that a fair percentage of deaths occurred in CR patients; we would highlight that these subjects, due to their old age and burden of comorbidities, often had died for causes unrelated to DLBCL or its therapy.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
