Adjunctive telmisartan treatment on body metabolism in clozapine or olanzapine treated patients with schizophrenia: a randomized, double blind, placebo controlled trial.
Trial report in Psychopharmacology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00981526 (Telmisartan as an Adjunctive Treatment for Metabolic Problems in Patients With Schizophrenia), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
objectiveThis study examined the effect of adjunctive telmisartan on body metabolism in clozapine- or olanzapine-treated patients with schizophrenia.
methodEach subject had been on stable dose of olanzapine or clozapine for at least 1 month. In a 12-week randomized, double-blind, placebo-controlled study, subjects received either telmisartan (80 mg once per day) or placebo. The homeostasis model of assessment of insulin resistance (HOMA-IR) was calculated based on fasting blood levels of insulin and glucose. Fasting blood levels of triglycerides and cholesterols, as well as serum levels of high-sensitivity C-reactive protein (hsCRP) and interleukin-6 (IL-6) were measured. The whole-body dual-energy X-ray absorptiometry (DXA) was used to assess body composition. Lipid particles were assessed using nuclear magnetic resonance (NMR) spectroscopy. All assessments were conducted at baseline and repeated at week 12.
resultsFifty-four subjects were randomized and 43 completed the study (22 in the telmisartan group, 21 in the placebo group). There were no significant differences between the two groups in week 12 changes for HOMA-IR or fasting triglycerides (- 0.18 ± 1.24 vs 0.39 ± 1.39, p = 0.181; - 26 ± 76 vs - 10 ± 81 mg/dL, p = 0.679, respectively) (telmisartan vs placebo). Further, there were no significant between group differences in week 12 changes for other fasting lipids, body weight, body mass index, waist circumference, as well as various measures of lipid particles (p's > 0.100). The DXA assessment showed no significant differences between the two groups in week 12 changes for fat mass, lean mass, or total mass (p's > 0.100).
conclusionIn the present study, adjunctive treatment of telmisartan did not seem to improve body metabolism in schizophrenia patients receiving olanzapine or clozapine. The implications for future studies were discussed. CLINICALTRIALS. GOV IDENTIFIER: NCT00981526.
