Correction: Undergraduate Medical Students’ Search for Health Information Online: Explanatory Cross-Sectional Study

In “Undergraduate Medical Students’ Search for Health Information Online: Explanatory Cross-Sectional Study” (JMIR Med Inform 2020;8(3):e16279) the authors noted errors in the presentation of the P values in the text of the Results section and in Table 1 of the published manuscript.

For the effected text in the Results section, under the "Sample" subheading, the following sentence was revised from:

There were 50 students randomly assigned to Google, 46 to Medisuch, and 44 to the free choice group (χ²₂₇₈=280.0 ,P P=).

To:

There were 50 students randomly assigned to Google, 46 to Medisuch, and 44 to the free choice group (χ²₂₇₈=280.0,P=.46).

And this sentence was revised from:

There were no significant differences between the groups with regards to age (F_2,135=5.04,PP=), gender (χ²₄=4.5,PP=), and previous formal medical or information technology (IT) training (χ²₂=1.5,PP=).

To:

There were no significant differences between the groups with regards to age (F_2,135=5.04,P=.008), gender (χ²₄=4.5,P=.34), and previous formal medical or information technology (IT) training (χ²₂=1.5,P=.23).

Under the "Information-Seeking Behavior" subheading, the following sentence was revised from:

However, students of the free choice group (mean 0.88, SD 0.79) reported significantly fewer pages as recommendable to patients than the other two groups (F_2,133=5.04,PP=; M_Google 1.55, SD 0.91; M_Medisuch 1.52, SD 1.53).

To:

However, students of the free choice group (mean 0.88, SD 0.79) reported significantly fewer pages as recommendable to patients than the other two groups (F_2,133=5.04,P=.008; M_Google 1.55, SD 0.91; M_Medisuch 1.52, SD 1.53).

This sentence was revised from:

Students in the free choice group opened significantly fewer recommendable pages (F_2,133=5.04,PP=).

To:

Students in the free choice group opened significantly fewer recommendable pages (F_2,133=5.04,P=.008).

And this sentence was revised from:

There was a highly significant difference between groups in whether or not the students entered specific medical terminology in the search engine (χ²₄=16.6,PP=).

To:

There was a highly significant difference between groups in whether or not the students entered specific medical terminology in the search engine (χ²₄=16.6,P=.005).

Under the "Quality of Webpages" subheading, the following sentence was revised from:

There were significantly high Pearson correlations between the number of webpages and the number of reliable webpages for all three groups (Google: r=.895; free group: r=.912; Medisuch: r=.860; allP P<).

To:

There were significantly high Pearson correlations between the number of webpages and the number of reliable webpages for all three groups (Google: r=.895; free group: r=.912; Medisuch: r=.860; all P<.001).

This sentence was revised from:

There were no significant differences in the frequencies of trustworthy webpages found among the three groups with χ²₁₄=16.45,PP=.

To:

There were no significant differences in the frequencies of trustworthy webpages found among the three groups with χ²₁₄=16.45,P=.29.

And this sentence was revised from:

With regard to the quotient of reliable webpages and all webpages found by students, again, no significant difference was shown (F_2,121=1.68,PP=) between the groups.

To:

With regard to the quotient of reliable webpages and all webpages found by students, again, no significant difference was shown (F_2,121=1.68,P=.19) between the groups.

Additionally, for Table 1, the P values in the far right column, under the heading "Chi-square (df)" have also been revised.

The "Histamine testing (wrong)" row was revised from:

1.03 (2),PP=

To:

1.03 (2),P=.60

The "Assessment of diaminoxydase (wrong)" row was revised from:

3.55 (2),PP=

To:

3.55 (2),P=.17

The "Test of urine and feces (wrong)" row was from:

0.84 (2), PP=

To:

0.84 (2),P=.66

The "Nutrition diary (correct)" row was revised from:

0.02 (2), PP=

To:

0.02 (2),P=.99

The "Elimination diet (correct)" row was revised from:

7.87 (2), PP=

To:

7.87 (2),P=.02

The "Provocation test (correct)" row was revised from:

0.06 (2), PP=

To:

0.06 (2),P=.97

The correction will appear in the online version of the paper on the JMIR Publications website on August 11, 2020, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories.
