Table 2 Comparison of Cochrane blogshots and PLSs regarding preference for presentation type perceived efficacy of described treatment and comprehension scores (n = 238)

Variable^a	Mean, 95% CI		Mean difference(95% CI)	P^b
Variable^a	Blogshot (n = 115)	PLS (n = 123)	Mean difference(95% CI)	P^b
Preference for health information presentation (score 2–20)	12.25 (11.10 to 13.24)	12.32 (11.34 to 13.33)	−0.03 (− 1.41 to 1.34)	0.963
Perceived efficacy of described treatment (score 2–20)	12.81 (11.91 to 13.72)	12.23 (11.22 to 13.19)	0.58 (−0.76 to 1.92)	0.395
Comprehension (score 0–8)	7.01 (6.64 to 7.38)	6.46 (6.08 to 6.85)	0.55 (0.02 to 1.074)	0.043

CI confidence interval, PLS plain language summary
^a The total score on perceived efficacy and preference for health information is calculated as the sum of scores for both summaries in respective groups. Comprehension is calculated as the sum of correct answers for two summaries
^bt-Test for independent samples
