The method of randomization was described in only 25% of published RCTs.
“For example, the method of randomization was described in only 25 % of published RCTs [10, 15, 22]”
From Impact of an online writing aid tool for writing a randomized trial report: the COBWEB (Consort-based WEB tool) randomized controlled trial (2015) · cites this paper as [22]
The Methods and results section reports that the allocation-concealment method was unclear in 61 of 234 trials (26%). The Comments section likewise says that about a quarter failed to describe how allocation was concealed—not that only a quarter described the method of randomization. The paper distinguishes allocation concealment from the randomization process and does not report the claimed 25% figure for randomization methods. (LLM, conf=0.87)
Checked by a reasoning model — may be wrong.
Experimental — accuracy not yet measuredPoor randomisation methods with no concealment can lead to exaggerated treatment effects.
“Poor randomisation methods with no concealment can lead to exaggerated treatment effects,79 80 which can then lead to further problems with overexaggerated systematic reviews.81”
From Novel ACT-based eHealth psychoeducational intervention for students with mental distress: A study protocol for a mixed-methodology pilot trial (2019) · cites this paper as [80]
The Methods and results section reports that trials with inadequate allocation concealment tended to yield statistically significant results more often than trials with adequate concealment; the Comments section reiterates that association. The paper compares P values, not the size of treatment effects, so it does not establish that poor concealment exaggerates treatment effects. (LLM, conf=0.84)
Experimental — accuracy not yet measured

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
