Abstract

Background: There is uncertainty about the efficacy of lamotrigine in bipolar depressive episodes. Aims: To synthesise the evidence for the efficacy of lamotrigine in bipolar depressive episodes. Method: Systematic review and meta-analysis of individual patient data from randomised controlled trials comparing lamotrigine with placebo. Results: Individual data from 1072 participants from five randomised controlled trials were obtained. More individuals treated with lamotrigine than placebo responded to treatment on both the Hamilton Rating Scale for Depression (HRSD) (relative risk (RR)=1.27, 95% CI 1.09–1.47, P=0.002) and Montgomery– åsberg Depression Rating Scale (MADRS) (RR=1.22, 95% CI 1.06–1.41, P=0.005). There was an interaction (P=0.04) by baseline severity of depression: lamotrigine was superior to placebo in people with HRSD score >24 (RR=1.47, 95% CI 1.16–1.87, P=0.001) but not in people with HRSD score 24 (RR=1.07, 95% CI 0.90–1.27, P=0.445). Conclusions: There is consistent evidence that lamotrigine has a beneficial effect on depressive symptoms in the depressed phase of bipolar disorder. The overall pool effect was modest, although the advantage over placebo was larger in more severely depressed participants.

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.
